本文对雷达制导的高空防空导弹提供了实际的设计考虑,讨论了对脱靶距离有重大影响的三个主要因素,即雷达信号回波、雷达寻的装置元件性能不理想,以及对导弹响应的各种限制。对高空目标,角闪烁是对雷达信号的主要影响。另外,寻的装置性能不理想(如框架不够稳定,天线罩折射斜率以及寻的装置陀螺对加速度敏感所引起的稳定性问题)和脱靶距离问题,这些都是制导系统设计者必须解决的问题。最后,导弹对制导指令的响应还受到加速能力的降低、响应时间的增加以及控制舵速率饱和的限制。下面将讨论脱靶距离对上述每个影响因素的敏感程度,此外,也提出了由于元件不理想所造成的不希望存在的各种反馈所引起的稳定性问题。对所研制的系统,如果要求在高空其性能指标必须满足,本文所提供的数值实例表明,在初步设计中实际硬件设备的缺陷是有重要影响的。
This paper provides practical design considerations for radar guided air defense missiles, and discusses three major factors that have a significant impact on the off-target distance, namely, the radar signal echo, the performance of radar-seeking device components, and the impact on missile response Kind of restriction For high altitude targets, flickering is the main influence on the radar signal. In addition, the performance of the seeking device is unsatisfactory (such as the frame is not stable enough, the radome refractive index slope and the gyroscope to find the device sensitivity to acceleration caused by the stability problems) and off-target distance, which are guidance system designers must solve the problem. Finally, the missile’s response to guidance commands is further limited by acceleration capabilities, increased response time, and control of the saturation of the rudder rate. The sensitivity of the off-target distance to each of the above-mentioned influencing factors will be discussed below. In addition, stability problems due to undesired various feedback due to the component’s non-idealness are also proposed. For the developed system, if its performance index must be satisfied at high altitude, the numerical examples provided in this paper show that the defects of the actual hardware in the preliminary design have a significant impact.
