| 摘 要： | 通过对宽带雷达信号目标回波特性的研究 ,在小信噪比情况下 ,对比分析了宽带雷达脉间相干积累和脉间非相干积累方法的性能 ,同时对多种不同信号检测方法在宽带雷达中的检测性能进行了对比研究。利用模拟的理想数据和实测数据进行仿真研究的结果表明 ,脉间、脉内均采用非相干积累的滑窗检测方法是一种性能稳定运算代价小的有效方法 ,且实现简单 ,有较强的工程应用价值。

| Abstract: | The characteristics of broadband radar reflected signals are analyzed. The performances of coherent accumulation and non-coherent accumulation methods in broadband radar are compared when the input SNR is small. At the same time. the preformances of several different signal detection methods in broadband radar are compared and studied. Simulation results using modeled and measured data prove that, sliding window energy accumlation detector with non-coherent accumulation is a stable and effective method and is very easy to realize. So it is very useful in project design. |
