摘要
高速运动目标,是现代雷达探测中遇到的一种新情况。针对海军相控阵雷达对海上空中高速运动目标的探测,推导了多元阵列的MIMO雷达探测概率的计算公式,在此基础上,计算了距离单元内目标探测概率,并比较了正交信号模式下与有向波束模式下MIMO雷达对高速运动目标探测概率。研究表明,对于高速运动目标,使用有向波束探测模式,在相同的信噪比下可以达到更高的探测效率。
The High-Velocity target is a new issue in terms of modern radar detect technology.Aim to search strategies of the naval phased array radar,the expression of detection probability was derived,the detection probability in a range cell was proposed based on that work,finally,a comparison of detection performance of a radar using a directed beam mode to that of a radar using orthogonal waveforms was given,it was shown that for higher-velocity targets,the use of scanning directed beams yields higher detection probability.
