摘要
为解决常规搜索雷达在强气象、地物杂波下目标检测性能下降的问题,基于目标先验信息,设计一种跟踪波束实现对特定目标的跟踪处理,对目标所在的波位采用参次中重复频率脉组的方式探测,有效扩展速度检测清晰区并抑制慢速气象杂波及强地物杂波,实现目标距离、速度双模糊的解算,提高对跟踪目标的检测性。基于先验信息实现目标距离、速度模糊解算,试验表明,通过采用基于参差中重频的脉组跟踪波束探测,能够提升搜索雷达对特定目标的检测能力,并实现重点目标的高精度测速,提高目标的航迹质量。
In order to solve the problem of the target detection degradation of conventional searching radar in strong weather and ground clutter,a tracking beam is designed based on the target prior information to realize the specific target tracking.The method of repeating frequency pulse-train in beam detection in stagger in the wave position where the target is located can effectively expand the speed detection clear area and can suppress slow weather clutter and strong ground clutter to achieve target distance and speed double fuzzy solution and to improve the detection capability of tracking targets.Based on the target prior information to achieve fuzzy solution of target distance and speed,the experiments show that by using repeating frequency pulse-train in beam tracking detection in stagger,the detection capability of the searching radar for specific targets can be improved,and high-precision speed detection of specific target can be achieved to improve target track quality.
