range-only radar的意思|示意

The target echo of passive radar based on FM signal has the characteristics of low SCR and narrow band. Only the receiver with large dynamic range can receive the weak echo signal.

基于FM信号的无源雷达目标回波信号信杂比低，频带窄，只有开发大动态范围的接收机才有可能接收到微弱的目标散射信号。

The airborne OTH target indication radar for ship born helicopter not only provides relay guidance and longer range, but also improves the missile attack accuracy.

舰载直升机机载超视距目标指示雷达不仅能为舰载导弹进行中继制导，延长导弹射程，而且能够提高导弹攻击精度。

The result of experiment shows that this method not only is efficient but also can visualize radar maximum detection range.

实验结果表明该方法不仅效率高，而且能真实直观地展现雷达最大探测范围。
