摘要:

在导弹半实物仿真系统中,微波暗室在提供模拟射频环境的同时,也给仿真系统带来了一定的误差.提出了一种暗室对导弹仿真系统影响的误差具体计算方法.通过对微波暗室环境建模,给出了从射频目标到暗室静区的能量计算方法,并利用数值积分的方法,分别计算得到了静区4个象限的能量值.根据比幅和差式单脉冲雷达测角原理,计算得到了导引头雷达的测角误差,并代入到导弹仿真系统中进行仿真.仿真结果表明,加入暗室误差后,导弹的轨迹发生了偏移,并使得导弹命中精度下降,但仍处于导弹命中误差范围内.

Abstract:

In the missile semi-physical simulation system, the anechoic chamber provides a radiofrequency simulation environment, and at the same time it brings an error for the simulation system. This paper proposes a specific error calculation method of the anechoic chamber on the missile simulation system. By modeling the anechoic chamber, it gives a computing method for quiet zone energy, and computes respectively energy for four quadrants of the quiet zone using numerical integration. Then according to the theory for angle estimation characteristic of amplitude comparison mono-pulse radar, this paper computes the angle error of radar on the seeker. Besides, the error is put into the missile simulation system. Simulation result shows that, when adding the anechoic chamber error, the trajectories of the missile and target both shift, decreasing the missile hit accuracy, but the error is still within the error range.

Key words: anechoic chamber, radiofrequency, quiet zone, missile simulation system, error
