摘要

在雷达接收机中进行脉冲压缩的手段之一是在发射机侧进行相位子脉冲调制。提出了一种用于相位子脉冲调制的未知序列估计方法，该方法在雷达干扰中具有重要的应用价值。在接收到的信号中检测到脉冲，这些脉冲随后用于评估协方差矩阵。证明了该序列可以由该矩阵的前两个特征向量重构

Blind Estimation of the Code Sequence in Spread Spectrum Radar

One of the means for pulse compression in radar receiver is the phase subpulse modulation at the transmitter side. The paper proposes an estimation method for an unknown sequence used for phase subpulse modulation, which is very important in radar jamming applications. Pulses are detected in the received signal, which are later used for evaluating the covariance matrix. It has been shown that the sequence can be reconstructed from the first two eigenvectors of this matrix
