速度多假目标干扰下,当雷达对机动目标进行跟踪时,会遇到虚假航迹较多、真-假目标鉴别难度较大、真实目标跟踪不稳定等难题,为此提出了速度多假目标欺骗干扰下基于速度估计径向投影和运动状态计数延迟的干扰识别方法。首先,采用速度量测和位置量测相结合的双通道机动检测方法,保证速度欺骗干扰下模型切换的准确性和及时性;然后,利用运动状态计数延迟的方法确定目标模型切换后跟踪稳定的时刻;最后,利用基于位置信息的速度估计径向投影构造检验统计量对速度欺骗进行识别。仿真实验表明,该算法具有较好的稳健性。 Under the condition of multi-fake jamming, when the radar tracks the maneuvering target, it encounters many problems such as more false tracks, more difficult to identify true-false targets and unstable real target tracking. Therefore, INTERFERENCE RECOGNITION METHOD BASED ON SPEED ESTIMATION OF RADIOGRAPHIC AND LATENCY COUNT DELAY UNDER FRAUD INTERFERENCE. Firstly, the two-lane maneuvering detection method based on speed measurement and position measurement is adopted to ensure the accuracy and timeliness of the model switching under the speed cheating jamming. Secondly, the method of motion state counting delay is used to determine the tracking stability after the target model is switched At last, we use velocity estimation based on location information to estimate the radial deception. Simulation results show that the algorithm has better robustness.
