Target Detection Performance of Spectrum Sharing MIMO Radars

Abstract: The demand for spectrum usage is increased which requires new spectrum allotments. For the coexistence of wireless system with the radar systems a dynamic allocation of spectrum method is proposed along with the noise power the communication system power is considered as interference power to the radar system. The communication power effect on radar system as a function of distance is analysed .A multiple input multiple output radar system and MIMO wireless communication system with K base stations are conside… Show more

“…3) Closed-form precoder design After estimating the interference channel, the precoder can be designed at either the radar or the communication's side. Similar to the zero-forcing (ZF) precoding of classic MIMO communication, a simple idea is the so-called null-space projection (NSP) [62], which typically requires the radar to have the knowledge of the ICSI. In the NSP scheme, the radar firstly obtains the right singular vectors of the interference channel matrix by singular value decomposition (SVD), and then constructs an NSP precoder relying on those vectors associated with the null space of the channel.…”

“…Remark 2: There might also exist targets that are neither significant scatterers in the communication channel nor of any interest to the DFRC BS. For notational convenience and following most of the seminal literature in the area [59], [62], [64], [66], [68], [98], we will not discuss such targets in detail and simply incorporate the generated interference in the noise term.…”
