"Comparisons have been made of the results of the detection performance of a space-based radar (SBR) system using uniformly-illuminated circular apertures, and the same apertures with Taylor weighting applied. From the studies, it is shown that the detection performance of an SBR system can be greatly improved with the application of the latter form of weighting. For the comparative studies, two antenna systems with the same physical dimensions were used, (1) a Taylor-weighted circular aperture for transmitting and receiving, and (2) a uniformly-illuminated circular aperture for transmitting, and the same aperture but with Taylor weighting applied for receiving. These comparative studies show that when antenna system (1) was used, 45.0 dB Taylor weighting was required in order to achieve the optimum SBR detection performance whereas for antenna system (2), 55.0 dB was required to give the same detection performance"--Abstract, page 1.
