• The Equivalence Among Three Approaches to Deriving Synthetic Array Patterns and Analyzing Processing Techniques

Publication Year: 1962, Page(s):116 - 119
Cited by:  Papers (4)
| |PDF (550 KB)

The equivalence of the vector addition, cross-correlation, and filtering approaches to deriving synthetic array patterns and analyzing processing techniques is demonstrated here. A mathematical model is defined which establishes a geometry, a transmitted and received signal, and a general synthetic array weighting function. A preliminary analysis of this model derives the signals received at the f... View full abstract»

• A Comparison of Techniques for Achieving Fine Azimuth Resolution

Publication Year: 1962, Page(s):119 - 121
Cited by:  Papers (25)
| |PDF (505 KB)

In the discussion of techniques for achieving azimuth resolution, it is instructive to compare the achievable resolution for three cases: 1) the conventional case for which λR Res = k / D 2) the unfocussed synthetic antenna case for which Res = k√λR 3) the focussed synthetic antenna case for which Res = kD where λ is wavelength, D is aperture of physical antenna use...

• Theory and Evaluation of Gain Patterns of Synthetic Arrays

Publication Year: 1962, Page(s):122 - 129
Cited by:  Papers (7)
| |PDF (1044 KB)

The results of an analysis of synthetic array gain patterns, including sidelobe response, are summarized. Both focused and unfocused arrays are examined. The phase time history of echos from reflectors on the ground as a function of position is used to modify the equations for the broadside synthetic array for application to forward-looking antenna arrays. The dependence of the optimal'' length ... View full abstract»

• The Effect of Normally Distributed Random Phase Errors on Synthetic Array Gain Patterns

Publication Year: 1962, Page(s):130 - 139
Cited by:  Papers (16)  |  Patents (1)
| |PDF (1147 KB)

In the practical formation of synthetic array patterns the individual signals which are integrated to form the array will sustain uncompensated phase shifts. If these uncompensated phase shifts are deterministic, the evaluation of their effect on the synthetic array radiation pattern is straightforward. On the other hand, if the uncompensated phase shifts are random, such as would be produced by p... View full abstract»

• Phase-Amplitude Monopulse System

Publication Year: 1962, Page(s):140 - 146
Cited by:  Papers (7)
| |PDF (2309 KB)

Phase monopulse, amplitude monopulse, and phase-amplitude monopulse are compared. The latter uses only two antenna feeds and by controlling the aperture illumination from these feeds has a separation of the illumination phase centers in one axis and opposed tilts of the phase fronts, or squint, in the other axis. It is described as more fundamental or less redundant than four-horn or other multiho... View full abstract»

• SCAMP-a single-channel monopulse radar signal processing technique

Publication Year: 1962, Page(s):146 - 152
Cited by:  Papers (6)
| |PDF (1157 KB)

A new monopulse radar signal processing technique is described, which requires only a single IF amplifer channel to instantaneously process the returns from all targets within a beamwidth. The basic signal processor consists of a wide-band amplifier-hard limiter, followed by appropriate band-pass filtering. The mathematical basis for its operation is developed and corroborating experimental result... View full abstract»

• Continuous-Wave Radar with High Range Resolution and Unambiguous Velocity Determination

Publication Year: 1962, Page(s):153 - 161
Cited by:  Papers (26)
| |PDF (1497 KB)

The conventional pulse radar has two shortcomings. First, since the pulse width and pulse repetition frequency are constrained by resolution and maximum range requirements, the average transmitter power can be increased only by increasing the peak transmitter power. Second, the limitation imposed by the sampling theorem prevents unambiguous measurement of Doppler frequencies higher than one half t... View full abstract»

• Sidelobe Suppression in a Range-Channel Pulse-Compression Radar

Publication Year: 1962, Page(s):162 - 169
Cited by:  Papers (18)  |  Patents (2)
| |PDF (1202 KB)

A model range-channel pulse-compression system is postulated and the problem of suppressing sidelobes in the compressed pulse is discussed. It is concluded that amplitude-weighting in the time domain (at IF) is a convenient method of suppressing sidelobes. An integration loss factor is defined which characterizes the decrease in signal-to-noise ratio (SNR) resulting from the inclusion of weighting... View full abstract»

• A Large Time-Bandwidth Product Pulse-Compression Technique

Publication Year: 1962, Page(s):169 - 173
Cited by:  Papers (12)  |  Patents (1)
| |PDF (821 KB)

A pulse-compression radar system which utilizes a linear FM waveform has a theoretical upper limit to the magnitude of its compression ratio or time-bandwidth product. This limit is a function of the observed target's relative radial velocity, and the effect on the return signal is characterized by both a pulse stretching and amplitude reduction if the limit is exceeded. The use of a logarithmic p... View full abstract»

• Optical Processing of Simulated IF Pulse-Doppler Signals

Publication Year: 1962, Page(s):174 - 178
Cited by:  Papers (5)
| |PDF (2616 KB)

The potentially wide bandwidth and large storage capacity of optical recording and processing systems leads naturally to consideration of direct IF recording. A method of recording and processing IF pulse-Doppler signals is presented and it is shown how ambiguities are reduced, compared to video processing, in the manner expected from sampling theory. Processing of a linearly varying Doppler frequ... View full abstract»

• An RF Multiple Beam-Forming Technique

Publication Year: 1962, Page(s):179 - 186

| |PDF (2724 KB)

An RF beam-forming matrix is described which forms n'' simultaneous beams from an n'' element array in a passive and theoretically lossless manner. The principle of operation is explained using some simple matrix configuration. A general expression for the far-field pattern of any beam is derived and then used to study the positions of beam peaks, the position of beam nulls, the crossover leve... View full abstract»

• Theory of Coherent Systems

Cited by:  Papers (6)
| |PDF (1692 KB)

A circuit theory model is derived for coherent radar, communication, sonar and antenna systems. The model involves linear time invariant operators and hence can be thought of as cascaded filters. The model provides insight for such systems not previously available, and it provides a unified approach to the analysis of all the above systems. The analysis is concerned with continuously distributed t... View full abstract»

| |PDF (1322 KB)

This paper presents an analysis of the problem of the resolvability of two radar targets which are located close together, in the sense that any parameters of the targets being measured (e.g., range, range rate, range acceleration, azimuth, azimuth rate, etc.) are close together. Arbitrary sets of parameters are allowed, and it is assumed there is additive noise of arbitrary but known spectral sha... View full abstract»

• Signal Fidelity in Radar Processing

Publication Year: 1962, Page(s):204 - 218
Cited by:  Papers (5)
| |PDF (4666 KB)

Usually in a radar signal-processing scheme, the primary consideration is the geometrical resolution of the system, or, if a particular measurement is desired, the accuracy of the system. Thus a given signal-to-noise ratio may be sought in order to meet a simple detection requirement or a desired accuracy. Usually, beyond these simple criteria, the matter of signal amplitude fidelity is not partic... View full abstract»

• Analysis of Signal Processing Distortion in Radar Systems

Publication Year: 1962, Page(s):219 - 227
Cited by:  Papers (4)
| |PDF (2111 KB)

Signal processing distortion degrades radar performance with respect to target data accuracy, ambiguity and resolution. A measure of the loss in performance is obtained by the development of a modified radar uncertainty function'' which results from the presence of time- and frequency-domain distortions in the system. Losses due to the major sources of distortion are evaluated and several compen... View full abstract»
