从天波超视距雷达探测目标信噪比伏大的实际情况出发,提出了一种适用的检测前跟踪(TBD)工程化算法。通过对信噪比起伏大的重点目标进行关联降门限检测,大幅提高了重点目标的检测概率。相比于常规的TDB算法,文中提出的算法原理更加简单,算法复杂度低,十分易于工程实现。

Based on the fact that the signal-to-noise ratio(SNR) of the target detected by sky-wave over-the-horizon radar fluctuates greatly,an applicable track before detect (TBD) engineering algorithm is proposed. The detection probability of the key target is greatly improved by detecting the correlation threshold of the key target with large fluctuation of SNR. Compared with the conventional TBD algorithm, the proposed algorithm has simple principle, lower complexity and is very easy to be implemented in engineering.
