| The algorithm of miss distance from the return wave of the multi-frequency Continuous Wave radar and its realization in engineering were discussed based on system of multi-frequency CW radar.Measure technical about miss distance have been studied and discussed; and the application of the muli-frequency CW radar system in the measure of miss distance was researched. The multi-frequency CW radar can orient the many targets by real time and realize the computation on the miss distance of the target. The algorithm of miss distance from the return wave of the radar was studied. The influence of measurement error about the target parameter on the measurement of the miss distance was analyzed and the influence of the target parameter in different measurement error on the miss distance was discussed. The theory was validated by the simulations.The application of the data process in radar was studied and discussed and the theories of filtering and the tracking that satisfy the reality were studied deeply too. The model of target motion, the technical of filtering and forecasting, all kinds of algorithm about data association, track initiation algorithm and so on were discussed. According to the demand of radar tracking in reality, NNF, Joint Probabilistic Data Association and EKF, UKF, track initiation algorithm and so on were studied on emphasis. Based on logic was applied, the good result of target tracking was obtained in the engineering application and the efficiency of the applied method was validated. |
