在分析中频解调原理的基础上,讨论了雷达情报侦察系统中脉內调制特性的分析方法。此外,就影响对不同的复杂雷达信号的脉内调制特性分析的因素进行了讨论。计算机模拟结果证明:在中频上解调分析雷达信号的脉內调制特性是简单可行的。
Based on the analysis of the IF demodulation principle, the analysis method of the in-pulse modulation characteristics in radar intelligence reconnaissance system is discussed. In addition, the factors that affect the analysis of the in-band modulation characteristics of different complex radar signals are discussed. Computer simulation results show that it is simple and feasible to demodulate the in-band modulation characteristics of radar signals at IF.
