    For good radar system performance, a transmitted waveform is desired that has 1) wide bandwidth for high range resolution and 2) long duration for high velocity resolution and high transmitted energy. In a pulse-compression system, a long pulse of duration T and bandwidth F (product of T and F greater than one) is transmitted. Received echoes are processed to obtain short pulses of duration 1/F.

    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»

    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»

    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»

    Doppler radars are employed for the detection of moving targets whose radar echo area is much smaller than the ground clutter return. Moving targets are separated from clutter on a frequency basis by utilizing the Doppler phenomenon. Continuous-wave Doppler radars have a practical maximum-range capability because the leak-through between the transmitter and receiver causes receiver saturation. Thi... View full abstract»

    Practical experience is now available with the Electron Beam Parametric Amplifier (EBPA) used as a low-noise preamplifier in radar systems. Principles of operation of the EBPA are briefly recapitulated. Among its desirable characteristics are unilateral behavior, high stable gain and a double-channel noise figure (NF) of 1 db or less; its bandwidth, input and output impedance remain constant as ga...

    The charged-particle intensity and energy distribution at the heart of the inner and outer Van Allen belts is compared with the experimentally determined radiation sensitivity of silicon solar cells. Energy dependence of the radiation damage and solar-cell characteristics is included in the lifetime estimate of spacecraft solar cells. Use of charged-particle range-energy relations and the differen... View full abstract»

    A brief introduction to coherent radar applications is given by discussing some basic pulse and CW systems. Comments on the historical development of these systems are followed by a general discussion of coherent radar parameter variations as they relate to the accuracy, resolution and ambiguity of target position or speed measurements.
