摘要
针对基于APD四象限探测器的激光半主动导引头对大动态目标跟踪过程中,自动增益控制使目标信号丢失和易饱和的问题,提出了一种根据实时回波信号的相关检测调整接收系统的自动增益控制方法。实验结果表明,应用基于相关检测的自动增益控制算法的激光半主动导引头可以更好的自适应于回波信号功率的变化,在宽动态范围内保证精确跟踪。
Aiming at the problem that the automatic gain control made the target signal lost and easy to saturate which occurred in the automatic semi-active seeker that based on the APD four-quadrant detector,a kind of real-time echo signal based on the correlation detection automatic gain control method for receiving system was proposed.The experimental results showed that the laser semi-active seeker based on correlation detection automatic gain control algorithm can better adapt to the change of the echo signal power and ensure accurate tracking in the wide dynamic range.
