经典的信息论准则估计信号源个数。 使用空间谱估计理论，模拟发射信号由天线阵列接受采样。经过AIC和MDL两种算法，估计出采样序列中信号的个数，所加噪声是白噪声。(Classical information theory for sources number estimation. It s spatial spectrum estimation theory. it analogs transmission signal from the antenna array . It uses two algorithms“ AIC and MDL ”to estimate the number of sampled signal sequence. the added noise is white noise.)

以下几个matlab程序对雷达常用的线性调频信号（lfm信号）进行脉冲压缩时的关键问题进行了仿真，其中包括旁瓣抑制影响（加窗与不加窗）、多卜勒频移影响，并对时域脉压与频域脉压结果进行了对比分析，供相关技术人员参考。(The following several matlab programs simulate the key issues when pulse compression is performed on radar commonly used chirp signal (lfm signal), including sidelobe suppression effects (window and windowless), Doppler frequency shift effects, and The time-domain pulse pressure and frequency-domain pulse pressure results were compared and analyzed for reference by the relevant technical personnel.)

About correlation. In signal processing, cross-correlation is a measure of similarity of two waveforms as a function of a time-lag applied to one of them. This is also known as a sliding dot product or inner-product. It is commonly used to search a long duration signal for a shorter, known feature. It also has applications in pattern recognition, single particle analysis, electron tomographic averaging, cryptanalysis, and neurophysiology.
