Algorithm Research Of Target Tracking And Miss Distance For Multi-Frequency Continuous Wave Radar System

Based on system of multi-frequency CW radar, the work of this dissertation is focused on the project implement of target tracking and study the arithmetic of miss distance with radar data.This paper studies and discusses comprehensively the applications of data processing techniques. It begins with studies of filter theory and target tracking theory, and continues to make deep discussion of such topics in the target tracking environment as target movement models, filtering and prediction, dynamic data association algorithms. For radar using purpose, The data algorithms for NNF and theα?βfiltering and prediction are studied emphatically. In the project, it adopts a kind of algorithm of track initiation based on logic-based method and tracking quality manage. The better results of project applications show that all algorithms are suitable for the multi-frequency continuous wave system radar.The system of radar is able to get the orientation of multitarget, so it can obtain the miss distance. This paper studies one kind of algorithm to get the miss distance with radar data, simulates the performance of this algorithm and application this algorithm to dealing with real time radar data. In this paper, we analyses the source of error, and improve its true using simulation.
