摘　　要：一般认为,岸基米波雷达由于受到海面多径反射的影响,波束上翘,难以进行海面目标的探测,关于米波雷达对海面目标探测性能的分析和论述较少。通过对电磁波在传播中经海面反射和沿海面绕射情况的分析,同时在海面反射和绕射之间进行合适的插值运算,给出了岸基米波雷达对海面目标的探测性能的分析和估算,并在某装备的研制中,进行了舰船目标的实际航行试验验证,试验结果与分析基本一致。对米波雷达的论证设计等具有借鉴意义。Because the strong influence of reflection on meter-wave propagation, meter wave radar beams are tilted up considerably. So it is difficult for shore-based meter-wave radar to detect maritime tar- gets. Little analysis has been done on the detection performance of maritime targets of shore-based meter- wave radar. The paper checks the factors of meter wave propagation in detail. Reflections and diffractions are computed together. A new method of interpolation is carried out between reflection zone and diffraction zone. The analysis is compared with the real data from a radar test. The computed data meets with the experiment result perfectly. This shows the analysis can provide useful reference for meter-wave radar design.
