摘要
后向投影 (BP)算法是一种被广泛应用于冲激SAR的成像算法。当冲激SAR的发射信号是某一类冲激信号时 ,根据冲激SAR成像的特点 ,推导出BP算法的方位分辨率与成像积累角、信号中心频率的关系。仿真结果表明 ,在相当范围内 。
Back projection(BP)algorithm is a popular imaging algorithm for impulse SAR. The relation between BP's azimuth resolution and azimuth angle as well as signal's center frequency is discovered when the radar's transmitted signal is one kind of impulse signal based on the characteristic of the impulse SAR imaging.The simulation results prove the estimation formula's validity.
