Abstract
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.
