摘要

分别对单测量能量探测拦截器和简单的狭缝能量探测拦截器进行了时跳扩频信号的可探测性评估。拦截器的探测概率被评估为虚警概率、几个被认为指定的系统参数以及通常由LPI系统设计者控制的时跳信号参数的函数。根据性能评估结果，讨论了调整可控参数以使LPI性能最大化的设计准则，以及BPSK或QPSK调制的选择对LPI性能的影响。

An LPI Performance Evaluation and Parameter Optimization for Time-Hop Spread-Spectrum Systems

The detectability of time-hop spread-spectrum signals is evaluated for both a single-measurement energy detection interceptor and a simple slotted energy detection interceptor. The interceptor's detecton probability is evaluated as a function of the false-alarm probability, several system parameters considered specified, and time-hop signal parameters that are usually controllable by the LPI system designer. Design guidelines for the adjustment of the controllable parameters to maximize the LPI performance, and the effect of the choice of BPSK or QPSK modulation on LPI performance is discussed in light of the performance evaluation results.
