Abstract

Abstract: The conventional method creates data with fixed cycle and discrete time.While analyzing the defect of the conventional method，a continuous-time method to generate multi-target data with exact “time stamp” is proposed.It concerns about the effect of relative tangent velocity between the targets and scanning beam，a group of equations are built to acquire the exact target data on the whole plane.Newton iterative method is used to get the answer.An approximate dealing is made in the tangent function’s singularity section.It can be used in Multiple Input and Multiple Output（MIMO） radar，phased array radar and the radar net simulation research，which have the variable sampling rate data.

Key words: time stamp, multi-target, Newton iterative, Multiple Input and Multiple Output（MIMO） radar, variable sampling rate

摘要： 针对以固定采样周期、时间离散生成的雷达目标数据不能提供准确目标“时戳”的缺陷，提出以连续时间方式生成含精确“时戳”的雷达多目标数据方法。该方法考虑了目标与雷达扫描波束相对切向速度的影响，建立雷达扫描波束与目标运动方程组，用牛顿迭代法求解，并在正切函数奇异区间作近似处理，获取整个平面的精确“时戳”目标点迹数据，可用于多输入多输出（MIMO）雷达、相控阵雷达以及雷达网中涉及到变数据率的数据处理仿真研究。
