跳頻電臺(tái)互調(diào)干擾估計(jì)的蒙特卡羅方法研究
[Abstract]:In the field of battlefield, the intermodulation interference generated between the intensive frequency-frequency equipment can cause severe distortion of the signal and influence the normal operation of the command communication control system (C3). The time, frequency and power condition of the intermodulation interference, as well as the influence of the random position and the shadow effect of the frequency-hopping radio station, are analyzed. The probability of the two or more active channels is studied, and the probability of the signal frequency in the active channel satisfying the intermodulation interference frequency condition and the probability of the signal power meeting the intermodulation interference power condition are studied. Based on this, an algorithm for estimating the intermodulation interference probability of the frequency hopping radio station based on the Monte-Carlo method is proposed, and the simulation results of the 3-order intermodulation interference of the two-way and three-way signals are simulated and verified respectively. The simulation results show that the method for estimating the intermodulation interference probability of the frequency-hopping radio station under the battlefield environment can effectively estimate the probability of the intermodulation interference, and the estimation result has certain guidance and reference for the electronic warfare simulation of the battlefield environment and the combat command of the battlefield.
