| 摘 要： | 针对海杂波背景下高频地波雷达的目标探测问题，采用时频分析方法研究对海杂波中的非平稳多分量目标探测。讨论了海杂波背景下的目标检测问题，以及信号的双线性时频分布，通过仿真研究了时频分布性能，尤其是核函数抑制多分量目标的交叉项作用。仿真结果显示，伪Wigner-Ville分布较Wigner-Ville分布对于交叉项的抑制作用较大，而平滑伪Wigner-Ville分布降低交叉项的效果更好。

| Abstract: | Aiming at the target detection of HF surface radar,the time-frequency distributing is selected to research on the nonstationary target detection.The bilinear time frequency distribution is discussed,especially the effect of kernel function in restraining the cross terms.The result of the modeling indicated the pseudo-Wigner-Ville distribution is better in the restraining and the smooth pseudo-WV distribution is the best in the all for restraining the cross-term. |
