The improved approaches for a single source direction-of-arrival estimation in a far-field and near-field cases are proposed. In the far-field case the multichannel maximum likelihood frequency estimation along the uniform linear array is used for direct calculation of the single real spatial frequency. In the near-field case the same method is applied for short sub-arrays for retrieving a set of...
Multiple-input multiple-output (MIMO) radars with wideband signals are useful to discriminate target in clutter. With wideband MIMO radar, the problem of extended target detection in compound-Gaussian clutter is considered in this paper. By obtaining target echoes from each antenna, the detector based on generalized likelihood ratio test (GLRT) is developed. It shows that the shape parameter of clutter,...
The problem of minimizing dwell time in multifunction phased array radar is considered. Target of interest is assumed to fluctuate according to a generalization of Swerling family and the parameters of fluctuation model are assumed to be known. The a'priori position of the target is uncertain. Optimization, whose variables include pulse count and array transmit beampattern, is carried out subject...
To measure the height of extended targets using radar wave multipath propagation, the line-of-sight (LOS) and the longest non-line-of-sight (NLOS) echos from a coherent target must be resolved accurately. This paper compares the performance of the recursive Fourier algorithm RELAX and the Method of Direction Estimation (MODE) algorithm for the purpose of multipath height finding. The main comparison...
