Design of simulation system for multi-function radar behaviour analysis

摘要

With the development and application of the multi-function radars (MFRs), it is imperative to analyse the behaviour for jamming decisions. Simulation software for MFR behaviour analysis is designed and developed for the purpose of recognizing the operating modes and predicting the future waveforms. The software is composed of three modules of training, recognition and prediction. The training module trains the radar model by training algorithm utilize the radar signal in the database, getting the prior probabilities and transition probabilities of multiple states; and the latter two modules recognize and predict the MFR behaviours by analysing the intercepted signals based on the pre-trained model. Simulations with a hypothetical MFR signal sequence in a typical scenario are presented, showing that the software is effective in extracting the characteristics and inferring the schedule schemes. The result is helpful in making intelligent jamming decisions, and supporting the adaptive radar countermeasures.
