为了提升舰船雷达远距离探测能力，更好保障舰船远距离航行任务顺利完成，提出舰船导航雷达远距离探测能力优化方法。基于扫描机制与面阵接收技术对舰船导航雷达架构实施合理设计，并在舰船导航雷达光学接收模块使用改进小波阈值法、中值滤波以及经验模态分解（EMD）算法，混合滤波接收到的舰船导航雷达回波信号，提升舰船导航雷达回波信号质量，实现舰船导航雷达远距离探测能力优化。结果表明，应用该方法能够优化舰船导航雷达远距离探测能力，相同量程下，可更好探测与呈现舰船航行过程中的远距离目标。
Propose an optimization method for the long-range detection capability of ship navigation radar, enhance the long-range detection capability of ship radar, and better ensure the smooth completion of ship long-range navigation tasks. Based on the scanning mechanism and array reception technology, a reasonable design of the ship navigation radar architecture is implemented. The improved wavelet threshold method, median filtering, and empirical mode decomposition (EMD) algorithm are used in the optical reception module of the ship navigation radar to hybrid filter the received ship navigation radar echo signal, improve the quality of the ship navigation radar echo signal, and optimize the long-range detection ability of the ship navigation radar. The experimental results show that the application of this method can optimize the long-range detection capability of ship navigation radar, and can better detect and present long-range targets during ship navigation at the same range.
