摘要:
防空领域中存在拦截目标速度高,控制时间短等难题。基于Simulink模块仿真,搭建激光末制导回路并构造该回路的伴随系统,仿真分析了随着弹-目接近速度不断提高,激光导引头在不同响应速度条件下,导引头角速度测量误差、角速度噪声以及导引律中的角度约束等因素所引起的脱靶量随末制导时间的变化规律。结果表明,提高激光导引头的响应速度能够有效降低弹-目接近速度提高所带来的影响。若弹-目接近的马赫数达到4以上,导引头带宽至少需大于80Hz,才能使得制导精度不会随着接近速度的提高而进一步的降低。
Abstract:
In the field of air defense,the speed of the intercepted target is high,and the control time we have is short. The laser terminal guidance loop was built as well as the adjoint system of the loop based on Simulink model,and the variation law of miss distance with terminal guidance time which was caused by measurement error,angular velocity noise and angle constraint of guidance law under the conditions of the approach speed of projectile and target continuously increasing and the laser seeker at different response speeds. The results of simulation show that it can effectively reduce the effect of the increase of approach speed of projectile and target to increase the response speed of the laser seeker. If the Mach number of the projectile approaching the target reaches 4 or more,the seeker bandwidth must be more than 80Hz so that the guidance accuracy will not decrease further with the increase of the approach speed.
