SARReturnWaveSignal
基于FFT的快速SAR分布目标回波模拟算法.
大面积分布目标的合成孔径雷达(SAR)回波模拟需要大量的运算，文中提出了一种合成孔径雷达回波模拟的快速算法，算法利用时域插值和FFTl’来缩减运算量，对于大面积目标回波模拟时，该算法有很高的效率。文中详细分析sinc函数插值所带来的误差以及补偿方法，并在次基础上提出了一种利用增采样插值方法，该方法以增加少量运算为代价，使得模拟精度的大幅度提高。文中比较了传统方法和基于FFTl’的快速SAR分布目标回波模拟算法的模拟结果，证明了这种快速算法确实行之有效。(The simulation of distributed targets is very important to the design of synthetic aperture radar(SAR)sys-
tems．Since the end product is SAR images，the echo of SAR signals needs to be simulated and then processed form SAR images，an d the parameters needs to be measured and the perform ance of the images should be，an d then evaluated．The designing parameters of SAR could be adjusted to meet the requirement of users before developing SAR systems，specially
in space—bome SAR systems．Th e simulation data is also needed during the developing an d debugging of a space—borne SAR real—time processor．Another purpose of simulation is to supply a great deal of simulation imag es to train image usors of space—bo rne SAR before it launch．)
