逆合成孔径雷达（ISAR）具有远距离、全天候、全天时工作等优点，目前通过ISAR成像来进行目标识别已得到广泛的应用。ISAR的观测对象是非合作目标，因此ISAR成像具有深远的国防应用背景，受到各国的重视，是竞争激烈、发展迅速的技术领域。(Inverse Synthetic Aperture Radar (ISAR) has a long-range, all-weather, all-time work, etc, currently conducted by ISAR imaging for target identification has been widely used. ISAR target non-cooperative target observation, it has far-reaching defense ISAR imaging application background, attention all, is highly competitive, rapidly developing technology.)

关于kmeans 的算法，和如何验证匹配准确率的算法(About kmeans algorithm, and how to verify the accuracy of the algorithm matches)

this is an e-book for signal processing based on matlab

使用FFT变换在频域对宽带扩频信号中的正弦干扰信号进行识别和抑制，其中扩频信号由1024点的伪随机序列表示。(In the frequency domain using the FFT transform of broadband spread-spectrum signal of sinusoidal interference signal identification and suppression, in which spread-spectrum signal is generated by pseudo-random sequence of 1024 points, said.)

针对双极性、单极性码产生直扩系统，并加上宽带噪声干扰，(For bipolar, unipolar codes have a direct expansion system, and with broadband noise,)

ccaf，cca分析，典型相关分析，主要是典型的相关类型分析。(ccaf, cca analysis, canonical correlation analysis, the typical types of analysis.)

CFAR一种门限设定方法，可以很好地对波动大的区域进行门限设定(CFAR of a threshold setting method, can be a good area for large fluctuations in the threshold setting)

很好的OFDM的基于MATLAB的仿真程序包，且包含了最终结果图.(montecarlo type montecarlo in the command window and wait for a long time.. _simulation of the complete OFDM system. _use of a very large file in order to get probabilities. _loop over different value of the noise. _compute the SNR for each value of the noise. _provide the SNR/BER plot. if you are in a rush : simulation_system !! go into the right folder and type simulation_system in the command window. _then type the value of the noise power (range = [-20,10]) _the function provides the channel estimation, the bit allocation, and a plot illustrating the errors. _this is a fast function (less pilot, no synchronization, small file).)
