A Direct Anti-high Repetition Jamming Design Method via The Minimum Interval Period Optimization

Semi-active laser detection is used extensively on many kinds of high-precision guidance weapon systems in the varied military fields. Although it is of high detection accuracy, this kind of detection mechanism, on the other hand, suffers from various laser interference modes which are added in view of the semi-active laser detection principle, covering from angle deception interference, synchronous forwarding interference, and high repetition frequency interference, etc. As a consequence, the overall performance is reduced accordingly. Among these types of deception interference, the high repetition frequency interference is the most effective one. In this work, to overcome this specific type of interference, a minimum interval period method (MIPM) is proposed to remove high repetition frequency interference and improve the detection accuracy of the laser semi-active guidance system. Numerical experiments validate that, this method is able to achieve good performance testing on the Semi-active laser detection under high repetition frequency interference via the False Alarm Probability (FAP for short) and Missed Alarm Probability (MAP).
