The response of a linear phased array with a matched filter connected at its output is investigated when a linear FM signal is incident on the array at an arbitrary angle. The filter is assumed to be matched to the linear FM signal. The dispersion produced by the array results in a mismatch at the receiver which depends on the scan angle and on the type of feed system used with the array. The distortion of the compressed pulse is studied for the series end-fed arrays, the series 相似文献

The dispersion effects that are produced when wideband linear frequency modulation (FM) signals are transmitted through a circular phased array are considered for both one-way and two-way transmissions through the array. The distortions resulting at the output of a matched fi'lter which is matched to the undistorted linear FM signal are studied. These distortions are 1) loss in peak pulse amplitude, 2) widening of the pulse, and 3) reduction in sidelobe level. 相似文献
