    A new eigenanalysis-based technique for direction estimation (and for estimation of the parameters of superimposed exponential signals from multiexperiment noisy data) is introduced. This novel technique, which is called MODE (method of direction estimation), offers the performance of the maximum likelihood (ML) method (the MODE and ML estimators coincide as the number of data samples increases) a...

  • Chebyshev-polynomial-based Schur algorithm

    Presents a new version of the well known Schur algorithm. The Schur algorithm may be used in a wide range of signal-processing applications, from stability tests for discrete time polynomials, through inverse problems and speech coding to the design of orthogonal digital filters. Since the algorithm is iterative in nature there is a tendency for roundoff errors to accumulate through the iterations... View full abstract»

  • Generalised approach to the design of narrowband antenna array processors with broadband capability

    Publication Year: 1990, Page(s):41 - 47
    Cited by:  Papers (1)

    A few techniques have been proposed for designing narrowband antenna array processors with a specific broadband capability. In one approach the array processor is designed by imposing on it a set of linear constraints. This set consists of two parts. In the first part, the processor is constrained to have unity gain in the desired look direction at the centre frequency of the frequency band of int... View full abstract»

  • Radar performance in a maritime environment: single hit detection in the presence of multipath fading and non-Rayleigh sea clutter

    Publication Year: 1990, Page(s):33 - 40
    Cited by:  Patents (2)

    The development of a statistical model which describes the radar backscatter characteristics of a point target, subject to multipath fading and non-Rayleigh, correlated sea clutter is presented. The model is based on the analysis of experimental observations of both forward- and back-scattering from the sea surface and hence has the attractive feature of being directly related to the physical mech...

  • Performance expectations of an airborne surveillance radar based on phase monopulse techniques

    Publication Year: 1990, Page(s):27 - 31
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (364 KB)

    In a surveillance or imaging radar, both coherent and noncoherent integration or averaging can be used as a means to increase the signal-to-noise power ratio. The paper examines the expected performance of a simple airborne radar based on a fixed antenna phase differential (monopulse) radar which uses noncoherent integration of pulses. Theoretical equations which describe the effects of noncoheren... View full abstract»

  • Effect of pulse length changes on Weibull clutter of sea ice

    Publication Year: 1990, Page(s):15 - 18
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (360 KB)

    Sea-ice clutter was measured using an X-band radar with pulse lengths of 0.08 and 0.3 mu s. It is shown that the amplitude of sea ice obeys a Weibull distribution with different shape parameters for both pulse lengths. The values of the shape parameter increase with increasing pulse length.<> View full abstract»

    Surprise has always been an important element of military tactics, and electronics must make its contribution to the element of surprise. It does this by radar, and by the various countermeasures that can be used against radar. The paper discusses the parallel development of radar and electronic countermeasures and shows how the battle between them has worked with the laws of physics to define mod... View full abstract»
