雷达定位中的脉冲压缩(Pulse Compression)是一种常用的信号处理技术,用于提高雷达系统的测距分辨率。在脉冲压缩中,常使用线性调频脉冲(Linear Frequency Modulated Pulse)或称为chirp信号来实现。 脉冲压缩的基本原理如下: 发射线性调频脉冲:雷达系统会发射一系列的线性调频脉冲。这些脉冲的频率会随时间线性变化,信号的
Space-time adaptive processingoperates on the two-dimensional angle-Doppler data for each range bin. Consider theK-by-N-by-Lradar data cube. Each of theKsamples is data from the same range. This range is sampled acrossNarray elements, andLPRIs. Collapsing the three-dimensional matrix at each...

预测编码中典型的压缩方法有脉冲编码调制(PCM,Pulse Code Modulation)、差分脉冲编码调制(DPCM,Differential Pulse Code Modulation)、自适应差分脉冲编码调制(ADPCM,Adaptive Differential Pulse Code Modulation)等,它们较适合于声音、图像数据的压缩,因为这些数据由采样得到,相邻样值之间的差相差不会很大,可以用较少位来...
