| Abstract: | For airborne E - scan monopulse radar, feasibility of a weight optimization computing idea of adaptive displaced phase center antenna （ADPCA） 1]is discussed, and the mechanism and difference of improving performance by using ADPCA methods in two frequency domains to introduce beam sharpening idea in Reference 2 ] are deduced in detail. The effect on ADCPA performed in time and frequency domains caused by compensating sptial phase shift, main clutter tracking and antenna subarray distances design is then discussed. And finally, computing time -consuming in two feasible projects is compared. |
