雷达信号处理中采用 DMTD 系统,能够大大提高抑制杂波的能力,但由于回波数量的大量减少,给方位角信息的提取带来了困难.本支详细分析了这种情况下方位角信息的提取,并推导出方位角精测的计算公式。对近似计算和影响精度的因素作了讨论.
The use of DMTD system in radar signal processing can greatly improve the capability of suppressing clutter, but the reduction of the number of echoes makes it difficult to extract azimuth information.This paper analyzes in detail the azimuth information Extraction, and derived azimuth precision calculation formula. The approximate calculation and the factors affecting the accuracy are discussed.
