说明：  在阵列信号处理中,可以对信号的来波方向进行估计,并计算其估计误差!(In array signal processing, the signal can be estimated to wave direction, and calculate the estimation error!)

计算了贝塞尔函数的一阶导数的零点。 更新BessDerivZerosBisect.m这些变化： 1。允许对m= 0 2。允许用户指定特定的m和k值理想。 3。允许公差输入参数 4。使用一个表的查找能为m和k的小值接近初始化 5。添加错误检查 6。计算衍生w.r.t.以X而不是w.r.t.米（虽然老方法的工作也。）(Calculates the zeros of the first derivatives of Bessel function. Updates BessDerivZerosBisect.m with these changes: 1. Allows for m = 0 2. Allow the user to specify the particular m and k values desired. 3. Allows for a tolerance input parameter 4. Uses a table look-up to get closer initializations for small values of m and k. 5. Adds error checking 6. Computes the derivative w.r.t. to x rather than w.r.t. m (although the old method works, too.))

合成孔径雷达回波模拟器的建模仿真与系统设计，首先介绍了合成孔径雷达的高分辨力成像原理、SAR回波理论模型和几种SAR原始回波数据模拟算法。然后采用距离时域脉冲相干法对点目标的原始回波数据进行了模拟，并用经典RD算法对该回波进行处理，得到了期 望的结果，本文还用同样的方法对点阵目标的原始回波数据进行了模拟。 (Synthetic aperture radar echo simulator modeling and simulation system design, first introduced high resolution synthetic aperture radar imaging principle, the the SAR echo theoretical model and several SAR raw echo data simulation algorithm. Domain pulse coherent method and then using the distance of the original point target echo data simulation, and the echo processing using the classic RD algorithm to get the desired results, this paper also used the same way the original dot target back wave data were simulated.)
