Abstract
A radar system has different modes of operation. In one mode, the radar operates as a single-input, multiple output (SIMO) radar system utilizing one transmitted signal from one antenna at a time. Codes with known excellent autocorrelation properties are utilized in this mode. At each receiver the response after correlating with various possible transmitted signals is measured in order to estimate the interference that each transmitter will represent at each receiver. The estimated effect of the interference from one transmitter to a receiver that correlates with a different code is used to mitigate the interference. In another mode, the radar operates as a multi-input, multiple-output (MIMO) radar system utilizing all the antennas at a time. Interference cancellation of the nonideal cross-correlation sidelobes when transmitting in the MIMO mode are employed to remove ghost targets due to unwanted sidelobes.
