摘要:

为提高稀布阵脉冲孔径雷达探测能力和小目标的发现概率,采用降低信号处理门限的方法,致使虚警概率高。常规方法难以完成目标航迹检测,需要通过TBD处理来完成目标检测。文中给出了基于多帧相关的TBD算法,利用目标的运动特性,通过对多帧数据的帧间相关处理,沿目标轨迹累积能量,从而提高信噪比,实现了在高虚警环境下的目标航迹检测。

Abstract:

In order to improve the detection range and small target detection probability of the SIAR (Synthetic Impulse and Antenna Radar),we reduce the threshold of signal processing system,resulting in a high probability of false alarm (usually 10-3).The conventional method fails to achieve track detection of the target,so we use the TBD.A TBD algorithm based on multi-frame correlation is introduced in this paper,which makes use of the target motion characteristics and the multi-frame data frame correlation processing to accumulate energy along the target track,thus improving the signal-to-noise ratio and achieving target track detection in the high false alarm environment.

Key words: SIAR;TBD;camera;multi-frame correlation;tracking detection
