[0065] Assuming that two types of sensors sensor1 and sensor2 are set to ESM and ELINT, the target is measured, and three types of target identity information are measured: radar carrier frequency RF, pulse repetition frequency PRF and pulse width PW, in which the sensor receives some kind of electromagnetic interference Make some data in the measurement data deviate from the real value, after the front-end data processing, after correlation, two target sequence matrices to be identified are obtained and , which are composed of three sequences, representing the three types of parameters RF, PRF and PW, and there are mutation points in the sequence due to interference. There are four types of target identity attributes in the target database, respectively using the sequence matrix , , and Indicates that the data parameters in the matrix and the target sequence matrix to be identified and Correspondingly, the lengths between them are unequal.
[0066] Using the DT...
