针对无人机在战场上的大量应用,为了进一步提高其在攻击目标时的瞄准精度,改善作战效能,提出了一种以PSD位置传感器为检测平台的用来验证无人机瞄准是否精确的方法。建立了等效于PSD的电阻电容网络,并根据相关的电路知识,推导了与之配套的数学公式,并利用数学软件对该数学模型进行了模拟,从中发现PSD电极输出信号的相位差与入射光斑位置存在近似的线性关系,通过实验研究结果表明,采用检测相位差信息来检测光斑位置的方法能够满足无人机瞄准精度检测的要求。并且信号处理的电路条理比较清晰,可以根据需要随时做出修改,使得系统的实用性有了一定的提高。
In order to improve the targeting precision of the UAV and improve the combat effectiveness, aiming at the large number of applications of the UAV on the battlefield, a method of using the PSD position sensor as a testing platform to verify the aiming of the UAV is proposed . Based on the related circuit knowledge, a mathematic formula is deduced, and the mathematic model is simulated by using mathematical software. It is found that the phase difference between the PSD electrode output signal and the incident The experimental results show that the method of detecting the position of flare by detecting the phase difference information can meet the requirements of aiming accuracy detection of the UAV. And signal processing circuit clearer, you can make changes as needed at any time, making the system has a certain degree of practicality.
