单通道红外制导系统已被成功地应用于小型战术导弹中。本文对单通道红外制导系统给出两个综合性表征参数:指令系数K_k和相位补偿角∑Φ。这两个参数从本质上代表了单通道红外制导系统的性能,并具有工程调试意义。在工程调试中,指令系数K_k表征了等效合成控制力的大小,它保证了导航比,可看作是最大合成控制力的利用程度;相位补偿角∑Φ表征了等效合成控制力的方向,它保证了控制的极性。从工程应用出发,针对某型产品对两个表征参数作出了具体计算,给出了实用数据,指出了调整方法。
Single-channel infrared guidance system has been successfully used in small tactical missiles. In this paper, two comprehensive characterization parameters of single-channel infrared guidance system are given: command coefficient K_k and phase compensation angle ΣΦ. These two parameters essentially represent the performance of the single channel infrared guidance system and have the meaning of engineering debugging. In engineering commissioning, the command coefficient K_k characterizes the magnitude of equivalent synthetic control force, which guarantees the navigation ratio and can be regarded as the degree of utilization of the maximum synthetic control force. The phase compensation angle ΣΦ indicates the direction of the equivalent synthetic control force , It guarantees the polarity of the control. Starting from the engineering application, the specific calculation of two characterization parameters for a certain type of product is made, practical data is given, and the adjustment method is pointed out.
