摘要
在传统的杂波计算中,将地表进行"等距离-等多普勒"划分。以雷达天线的发射、接收理论和雷达的目标散射理论为基础,推导出合成孔径雷达杂波功率谱的计算公式,并对公式的闭合积分解和实时算法进行了讨论。
In traditional methods for calculating ground clutters, the ground is always partitioned by ＂range-doppler＂ curves. Based on sending-receiving theory of radar aetenna and radar target scattering theory, the clutter power spectrum density （PSD） computation formula for synthetic aperture radar （SAR） has been derived in detail, furthermore the close-form integral solution and the real-time arithemetic for the formula are also discussed.
