摘要
针对远距离压制干扰下机动目标跟踪问题,分析了远距离大功率压制干扰对于雷达探测及测量精度的影响,引入新的量测模型模拟雷达在压制干扰下由于探测概率下降出现的目标暂消现象,并利用去相关无偏量测转换方法将球坐标下的量测转换到直角坐标系下。在此基础上,基于自适应联邦滤波的思想建立了雷达压制干扰下的机动目标跟踪算法。仿真结果表明,在远距离压制干扰下,所提方法可以保持对目标在多种机动情况下的稳定、准确跟踪,与现有方法相比具有明显的优势。
To realize the tracking of maneuvering targets in the presence of long-range suppression jammingthe influence of long-rangehigh-power suppression jamming on radar detection and measurement accuracy is analyzed.A new measurement model is introduced to simulate the temporary disappearance of the targets caused by the decrease of detection probability of the radar in the presence of suppression jamming.The measurement in spherical coordinates is converted to measurement in right angle coordinates by using the decorrelated and unbiased measurement conversion method.Thena maneuvering target tracking algorithm under suppression jamming on the radar is established based on the adaptive federal filter.The simulation results show thatthe proposed method can maintain stable and accurate tracking of targets in a variety of maneuvering situations under long-range suppression jammingwhich is obviously superior to the existing methods.
