Abstract:

Aiming at the problem of radar and electronic support measurement (ESM) track correlation under asynchronous conditions, a track correlation algorithm without time domain registration is proposed by analyzing the influence of asynchronous measurement values of the azimuth on the principle of cross location. According to the difference of sensor's delay and sampling rate, the isometric interval transformation of the unequal length track sequence and the interval method of asynchronous track cross location are presented. Track correlation of heterogeneous sensors is realized by calculating interval sequence discrete degree. Through simulation verification, the interval sequence discrete degree is not affected by the noise distribution, and the solution of the overall characteristics of the data set avoids the point-by-point operation in the traditional algorithm, which effectively improves the algorithm calculation rate. Compared with the traditional algorithm, the asynchronous track can be correlated directly and accurately under a variety of measurement error scenarios.

Key words: track association, cross location, radar, electronic support measurement (ESM), interval transformation
