Signal design based on post‐detection SINR for MIMO radar in the presence of signal‐dependent interference
Abstract In this study, the target detection and signal design problems in the presence of signal‐dependent interference for a colocated multiple‐input multiple‐output (MIMO) radar employing a space‐(slow) time transmit signal are addressed. Due to the large dimension of the clutter covariance matri...

| description | Abstract In this study, the target detection and signal design problems in the presence of signal‐dependent interference for a colocated multiple‐input multiple‐output (MIMO) radar employing a space‐(slow) time transmit signal are addressed. Due to the large dimension of the clutter covariance matrix (CCM) in MIMO radars, the Kronecker form of the CCM is exploited to derive a Rao‐based detector, which does not require the secondary data. According to the numerical results, the proposed detector considerably outperforms its competitors. Additionally, by tackling a non‐convex sum of ratio problem, a low‐complexity algorithm is devised to maximise the post‐detection signal‐to‐interference‐plus‐noise ratio (SINR) under constant modulus and similarity constraints. Finally, using the simulation results, the effectiveness of the designed signal on the system performance is highlighted. |
