MATLAB跳频仿真源代码，展示了整个跳频通信过程，包括信号源产生、2FSK调制、跳频扩频、跳频解调、2FSK解调、抽样判决、恢复原始信号过程，适合初学者(MATLAB frequency hopping simulation source code, showing the entire frequency hopping communication process, including signal source generation, 2FSK modulation, frequency hopping spread spectrum, frequency hopping demodulation, 2FSK demodulation, sampling decision, restoration of original signal process, suitable for beginners)

脉冲压缩的匹配滤波。目标距离分别为10米，30米和100米，对于未压缩的脉冲，三个回波信号混叠在一起，不能分辨，而经过脉冲压缩的脉冲信号则可通过匹配滤波收到3个回波信号(Matched filtering for pulse compression.Target distances are 10 metres, 30 metres and 100 metres, respectively. For uncompressed pulses,The three echo signals are overlapped and can not be distinguished. While pulse compression can distinguish three echo signals after matched filtering)
