摘要
针对P波段雷达在天线阵面规模(单元数)一定情况下,波束宽度较宽,测角精度不高,无法满足跟踪制导精度要求的问题,文中探讨了利用多个P波段雷达组网来提高系统精度以达到跟踪制导要求的问题,并详细分析了多部雷达联合定位后的距离、方位和俯仰精度,提出了用IMM+EKF和IMM+UKF点迹融合算法提高系统精度,最后仿真验证了方法的有效性。
Aiming at the problem that P-band radar cannot satisfy control and guide function due to its wide wave and poor angle preci- sion with restricted antenna unit, a method of multiple P-band radars data fusion is presented. Precision of distance, azimuth and pitch- ing is analysed detailedly. A method is proposed for improving system precision using IMM ＋ EKF and IMM ＋ UKF point fusion. At last simulation results are given. The results show that the precision of multiple P-band radars data fusion is excellent.
