Analytical Solutions to Thresholds of Association of Measurements with Radar Tracks

Turnk和Wilson在文献[1]中提出了一种新的多门限雷达和DF（Direction-Finding）互联算法，该算法特别适宜于雷达和DF航迹是由不等样本容量的观测所构成的场合文献[1]中，相关决策门限是通过MonteCarlo仿真得到的，因而在获得决策门限时需要较多的时间.我们对文献[1]算法的决策门限进行了研究，推导出了这些决策门限的解析表达式，利用数值计算方法得到了这些决策门限的解析值，结果表明了算法的有效性最后，对互联算法进行了仿真实验．

Trunk and Wilson proposed an algorithm for associating the DF (Direction-Finding) measurernents with radar tracks in [1],which is suited for the situations where both radar and DF traks are specified by different numbers of measurements. In 1he algorithm of [1], the decision thresholds were obtained by using Monte Carlo simulation techniques. The analytic expnaions of the deicsion thresholds in [1] are derive based on statistical theory, and the results are obtained by using numerical method.The computational results show that the analytical expressions are correct, and that it takes much less time to obtain the values of the thresholds by using the derived analytical expressions. Finally, simulation is made with satisfactory results.
