提出了一种基于改进的交互式多模型粒子滤波（IMMPF）跟踪方法的雷达能量控制策略。首先，通过增加与系统状态接近的粒子的权值和更新每个粒子的模型概率来改进IMMPF跟踪方法。基于改进的IMMPF方法，提出了一种低截获概率（LPI）能量控制方法，即在检测概率不变的情况下，根据目标的距离和雷达散射截面（RCS）大小，控制雷达的发射时间和发射功率。蒙特卡洛仿真结果验证了算法的跟踪精度和低截获概率性能。通过与其他方法的比较，验证了该方法的有效性。
A novel radar energy control strategy based on an improved Interacting Multiple Model Particle Filter (IMMPF) tracking method is presented in this paper. Firstly, the IMMPF tracking method is improved by increasing the weight of the particle which is close to the system state and updating the model probability of every particle. Based on this improved IMMPF method, an energy control method for Low Probability of Intercept (LPI) is then presented, which controls the emission time and power of radar according to the target's range and radar cross section (RCS), under the condition of constant detection probability. The tracking accuracy and LPI performance are demonstrated in the Monte Carlo simulations. The results are validated through the comparisons with other methods.
