In this paper we consider the issue of adaptive transmission and detection for MIMO radars operating under clutter with unknown covariance. In particular, we show that the availability of a set of secondary data allows defining Constant- Transmit . Receive False-Alarm Rate (CFAR) receivers starting upon a family of previously known non-adaptive structures. We also show that, if the clutter correlation remains constant in several scans, an adaptive waveform selection procedure can also be imple- mented. The results show that the adaptive transmit/receive structures perform satisfactorily in comparison to their nonadaptive counterparts, the loss being in the order of 2 - 3 dB's for customary values of the system parameters.

Abstract
In this paper we consider the issue of adaptive transmission and detection for MIMO radars operating under clutter with unknown covariance. In particular, we show that the availability of a set of secondary data allows defining Constant- Transmit . Receive False-Alarm Rate (CFAR) receivers starting upon a family of previously known non-adaptive structures. We also show that, if the clutter correlation remains constant in several scans, an adaptive waveform selection procedure can also be imple- mented. The results show that the adaptive transmit/receive structures perform satisfactorily in comparison to their nonadaptive counterparts, the loss being in the order of 2 - 3 dB's for customary values of the system parameters.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
