基于BP算法的机载SAR点目标matlab仿真程序(The matlab code is about point target simulation of airborne SAR based on BP algorithm)

Perfect for the beginner, this demo illustrates simple object detection

运放电路分析，非常实用，简单易懂，有图解分析。(Op amp circuit analysis, is very practical, easy to understand, there are graphic analysis.)

Alamouti Code to achieve diversity without channel knowledg at the transmitter It is assumed that system contains 2 transmit antennas and one receive antenna.

主要介绍了舰船辐射噪声的生成，包括宽带连续谱和线谱的建模仿真，得到了不错的效果(Mainly introduces the generation of ship radiated noise, modeling and simulation, including broadband line spectrum and continuous spectrum, obtained good results )

根-多信号分类算法（MUSIC）求电波到达角、离开角(Root- multiple signal classification algorithm (MUSIC) seeking wave arrival angle, left corner)

MTI，LFM脉冲串信号，对多目标回波进行脉冲压缩，再进行MTI。(MTI, LFM pulse train signal, multi-target echo pulse compression, then MTI.)

1．用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图 2．进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选 3．做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱 4．用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图(1. Produce sine wave, square wave, and the white noise signal with Matlab, and their time-domain waveform display 2. FFT transform, display each spectrum, where the sampling rate, frequency, length optional data 3. RMS to make maps of the three signals, power spectrum, as well as the number of RMS map 4. Restored by inverse Fourier transform IFFT signal and displays the time domain waveforms sinusoidal signal recovery)
