摘要
针对机载电扫单脉冲雷达,探讨一种自适应偏置相位天线(ADPCA)[1]优化权值计算思路的可行性,并详细推导文献[2]中两种频域ADPCA方法引入波束锐化思想提高性能的机理和区别。其次讨论补偿空间相移、主杂波跟踪及天线子阵间距设计对时频域ADCPA性能的影响。最后给出了两种可行方案的计算耗时比较。
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.
