| 摘 要： | Golay互补码和Alamouti空时编码相结合的极化测量方法,能有效地解决全极化测量波形自相关与互相关函数相互制约的矛盾。针对这种测量方法,设计了一种具有多普勒补偿能力的全极化雷达接收机信号处理方案,重点分析了多普勒频移对接收机性能的影响,仿真结果表明该方案在目标多普勒频移比较大的情况下,仍然具有比较好的性能。此外,该设计结构简单,易于工程实现。

| Abstract: | The method,making good use of Golay complementary codes and Alamouti space-time codes,can eliminate the conflict between autocorrelation and crosscorrelation of waveforms for full radar polarimetry.According to the polarimetric measurement method,a simple signal processing mechanism with doppler compensation for the receiver is considered and analysed.The simulation result presents that it can attain good performance when the doppler shift induced by the movement of target is large.Additionally,the architec... |
