SAR-IMAGING---
成像处理一般包括三个步骤:1、距离向脉冲压缩,对一个合成孔径内的每个回波脉冲均进行压缩;2、距离徙动矫正,把属于同一点目标的脉冲校正到等距离线上、3、方位向脉冲压缩。(Imaging process generally comprises three steps: a distance to the pulse compression of echo pulses each have an inner aperture compression 2, range migration correction, the pulses belonging to the same point in the correction target line equidistant , 3, azimuth compression to pulse.)

Auto_Measure_system
利用ccs环境、MATLAB环境、DSP(TMS320F2812)、被测对象和Agilient网络分析仪E5071B,构建一个自动测量系统。
相信大部分人都知道基于NI公司的GPIB总线,可以实现自动测量,但NI公司的方案实在太昂贵,采用MATLAB能够大大降低成本。matlab与ccs之间基于RTDX协议进行数据交换,同时matlab基于TCP/IP协议与E5071B之间通信,源码说明如下:
(1)RTDX_ok目录:matlab7.0代码,包含了一个用GUI实现的界面和相关的具体代码,特别是在其中实现了SCPI语言来对仪器进行控制。
(2)TMS320F2812目录:包含ccs下的c代码,如果没有做过RTDX的应用,相信这个对你很有启发。(Use ccs environment, MATLAB environment, DSP (TMS320F2812), the measured object and Agilient network analyzer E5071B, construct an automatic measurement system. I believe that most people are aware NI' s GPIB-based bus, you can realize automatic measurement, but NI' s program is too expensive, the use of MATLAB can greatly reduce costs. ccs between matlab and RTDX protocol-based data exchange, while matlab based on TCP/IP protocol and communication between the E5071B, the source described as follows: (1) RTDX_ok directory: matlab7.0 code, contains a GUI implementation with the interface and specific code, especially in one of implementation of the SCPI language to control the apparatus. (2) TMS320F2812 directory: contains ccs of c code, if not done RTDX application, then I think it was very instructive for you.)
