为更准确检验与评估采用被动微波/红外复合制导模式的舰空导弹制导系统性能,需要对影响制导精度的主要因素进行深入分析。文中建立了被动微波/红外复合制导系统精度一般模型,通过对实际复合制导失利案例的详细分析,研究了被拦截目标的微波辐射特性与红外特性对该类复合制导系统精度的具体影响,指出影响该类制导系统精度的主要因素为目标微波辐射特性和红外特性,从而为制导系统和实际试验鉴定中目标特性的设计提供参考。

For more accurate test and evaluation of guidance system performance of ship-to-air missile using passive microwave /infrared compound guidance mode, main factors that affect guidance precision were required for analysis, In this paper, passive microwave / infrared compound guidance system's accuracy model was established, through detailed analysis on compound guidance failure case, specific impact of the intercepted target's microwave radiation and infrared characteristics on the composite guidance system's accuracy was studied. It is pointed out that the main factors which affect precision of the guidance system are the microwave radiation and infrared characteristics, which can offer reference for design of guidance system and target characteristics in test evaluation.
