针对以往判定目标点是否被雷达发现的算法精度较低、易产生时间错位、影响生成的点迹质量等问题,提出了一种新算法,用于雷达模拟器中实现模拟场景和真实场景的叠加,并对固定和运动雷达平台情况进行了讨论.新算法首先判断雷达扫描线是否发现目标,然后根据目标和扫描线的速度列出相应的超越方程,再用二分法获得在精度要求之内的点迹发现时间.仿真实验结果表明,该算法易于实现,可根据精度需要产生相应的结果.

Aimed at the problems that the previous algorithm accuracy for determining whether the target has been discovered by radars is lower, easy to bear time dislocation and affects the quality of generated radar plot, this paper proposes a new algorithm applied to implementing the superposition of simulated scene and real scenario in a radar simulator, and discusses the cases of fixed and moving radar platform, respectively. In this new scheme, whether the radar scanning lines has discovered the targets is firstly determined, then the corresponding transcendental equation is listed in terms of the velocity of target and scanning lines, and finally obtain the plot discovery time within the precision requirements using the bisection method. Experimental results illustrate that this proposed new algorithm is easy to implement and generates the corresponding results by the required precision.
