帧间码参差解距离模糊方法

针对现有测量系统中常用参差码测距解模糊方法的不足,提出了帧间码参差解距离模糊的方法。采用时间、径向距离、方位、俯仰、径向速度相关方法,结合航迹处理的预测数据,通过帧间码参差解出距离模糊,克服了常用参差码测距解模糊的缺点,并在一定发现概率和虚警条件下,对目标匀速直线、匀加速直线、抛物线、匀速圆周、曲线运动情况进行了仿真。统计分析结果表明,该方法是有效的。

Method for Range Ambiguity Resolving Based on Inter-frame Staggered Code

In current measurement system,methods resolving range ambiguity based on staggered code are commonly used.With their disadvantages considered,a method resolving range ambiguity based on inter-frame staggered code is presented.This method,adopting time,radial range,azimuth,elevation and radial velocity correlation methods and combining with prediction data of track processing,resolves the range ambiguity through inter-frame straggered code and overcomes the disadvantages of commonly used methods.Moreover,in the presence of given detection probability and false alarm probability,rectilinear motion with constant velocity,rectilinear motion with constant acceleration,parabolic motion,circle motion with constant velocity and curvilinear motion are simulated.The statistical analysis results show that the method is effective.
