首先，对侦察雷达所能探测到的目标雷达信号的载频、脉宽、重频，应用证据理论将其组合，得到雷达参数的联合概率分配函数。

Firstly, the obtained radar signal radio frequency, pulse width, repeat frequency are composed to get a combined probability assignment function of radar parameters by applying D-S method.

低截获声纳通过选择合适的发射信号，在保持探测能力的同时，降低被敌方侦察声纳截获的概率。

Low probability of interception (LPI) sonar selects appropriate transmitting signals and reduces the probability of being intercepted by hostile scouting sonar while it maintains detection capability.

深弹引信在对目标进行探测的过程中会遇到来自邻近深弹回波信号的干扰，邻弹干扰是导致虚警概率增加的最主要因素。

In the process of target detection, depth bomb fuze will undergo the interference from echo signal of neighborhood bomb that is the primary factor which causes high false-alarm probability.
