Target models and waveform design for detection in MIMO radar

Abstract: In this paper, we propose a general target model for multiple-input multiple-output (MIMO) radar. Two types of targets are presented. For each type of target, we develop a corresponding optimum waveform designing method to optimize detection performance. Based on Chernoff-Stein lemma, we use relative entropy as the performance measure. We show that the optimum waveform designing method can obtain better detection performance than traditional orthogonal waveform designing method.Keywords MIMO radar, waveform de… Show more

“…We derive the optimal Neyman–Pearson (NP) detector for the associated target detection problem. With a similar consideration to that in [14, 16, 17] (i.e. the waveform design based on maximising the probability of detection is difficult), we resort to the relative entropy associated with the detection problem as the design metric.…”

“…In the literature, various works which optimize the waveforms of radar signals for detection performance enhancement have been proposed [6], [7]. Based on the optimization criterions, these works can be broadly classified into three types: detection probability, signal-to-interference-plus-noise ratio (SINR), and relative entropy based schemes [8].…”

According to [26], the gain of the double cascaded channel can be roughly expressed as A/(d 2 1 d 2 2 ), where A is a parameter related to the gain of the RIS, d 1 denotes the distance between the antenna and the RIS, and d 2 denotes the distance between the RIS and the targets.…”

“…Specific to the field of MIMO radar, existing works pertaining to waveform design for collocated MIMO radar are mainly carried out under certain energy constraint [3][4][5]. As for MIMO radar with widely spread antennas, although such systems often resort to orthogonal transmitted waveforms, it is still possible to reduce the power budget to a certain degree via power adjustment among multiple transmitters.…”
