摘要

讨论了正交信号MIMO雷达在抗到达时差方面的优势。首先分析了两个接收机在不同方向上接收到的信号相对于MIMO雷达的相互关系。结果表明，在一定的角度差值下，相互关系发生变化，两个信号甚至完全不相关。然后详细分析了基于均匀线性发射阵列(ULTA)的步进频分线性调频(SFDLFM)信号的角范围耦合。角距耦合最终会导致定位偏差，从而影响雷达的射频隐身能力。

An analysis of anti-TDOA positioning capability for MIMO radar

The advantages of MIMO radar with orthogonal signals in anti-TDOA (Time Difference of Arrival) are discussed. First the cross-correlation between signals received by two receivers in different directions relative to MIMO radar is analyzed. It shows that the cross-correlation changes with the angle difference in certain value of which the two signals are even completely uncorrelated. Then a detailed analysis of angle-range coupling is presented based on uniform linear transmit array (ULTA) when Stepped Frequency Division Linear Frequency Modulation (SFDLFM) signals are used. The angle-range coupling will ultimately lead to the positioning deviation, thus contributing to the radar RF stealth.
