在工程应用中 经常会遇到一些复杂的非线性系统, 这些系统状态方程复杂, 难以 用数学方 法准确建模。 在这种情况下, 可以 建立 BP 神 经网 络表达这些 非 线 性系 统。 该方法把未 知 系 统看成是一个黑箱, 首先用 系 统 输入输出 数据 训 练 BP 神 经网 络, 使网 络能 够表达该未 知 函 数, 然后就可以 用训练好的 BP 神经网络预测系统输出 。 本章拟合的非线性函 数为 y = x1^2+x2^2. 。 (In engineering applications often encounter some complex nonlinear systems, which complicated the equation of state, can not be accurately modeled mathematically. In this case, BP neural network can be established to express these nonlinear systems. The method of the unknown system as a black box, the first input and output data with systematic training BP neural network, the network can express the unknown function, then you can use the trained BP neural network forecasting system output. Chapter for fitting non-linear function y = x1 ^ 2+x2 ^ 2..)

RD算法实现，包括低斜视角和大斜视角（SRC方式2、SRC方式3）两种情况，系统固有参数见《Digital Processing of SAR Data》一书。(RD Algorithms implementation, including low squint case and high squint case.Parameters refer to 《Digital Processing of SAR Data》.)

提高MAtlab编程技巧 书中主要以实例形式进行介绍，简便易学，是一本不可多得的好书(Improve you matlab skill: Many of the examples in the fi rst half of the book are not idiomatic MAT- LAB. I address this problem in the second half by translating the examples into a more standard style.)
