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．)

滤波法
A、名称：限幅滤波法（又称程序判断滤波法）
B、方法：
根据经验判断，确定两次采样允许的最大偏差值（设为A），
每次检测到新值时判断：
如果本次值与上次值之差<=A，则本次值有效，
如果本次值与上次值之差>A，则本次值无效，放弃本次值，用上次值代替本次值。
C、优点：
能有效克服因偶然因素引起的脉冲干扰。
D、缺点：
无法抑制那种周期性的干扰。
平滑度差。(A. Name: Limited filter method (also known as program judgement filter method)
B. Method:
Based on experience, the maximum allowable deviation (set to A) of two sampling times is determined.
Judge each time a new value is detected:
If the difference between the current value and the previous value is <=A, the current value is valid.
If the difference between the current value and the previous value is greater than A, then the current value is invalid, abandon the current value and replace the current value with the last value.
C. Advantages:
It can effectively overcome the impulse interference caused by accidental factors.
D. Disadvantages:
That periodic interference cannot be suppressed.
The smoothness is poor.)
