摘要
针对传统正交插值和脉冲压缩处理方法中存在的脉压结果主瓣不对称和峰值相位非线性问题,分析了DFT频率泄漏和脉压系数的设计对此问题的影响,设计了改进的算法并进行了仿真,比较了新算法与传统算法性能的优劣,给出其在实际应用中的意义。
There exist two problems in the traditional algorithm of quadrature sampling and pulse compression.One is that the main lobe after pulse compression is not symmetrical in amplitude,the other is that the phase difference between two adjacent peaks is nonlinear. In this paper, the impact of the frequency leak in DFT and the design of pulse compression coefficient are analyzed,and the improved algorithm is designed and simulated. Finally the superiority of the new algorithm over the traditional one is stated with its practical application presented.
