Multi-signal radar cross-talk mitigation

A computer-implemented signal process method for identifying a target amid clutter and minimize cross-talk from a plurality of receive signals returned therefrom via a Multiple Input Multiple Output (MIMO) radar system that emits a plurality of transmit signals into a resolution cell that contains said target and said clutter, said method comprising:

• employing a match filter to estimate a target set of parameters from each receive signal of the plurality of receive signals;
• determining interference correlation RIq′ for q′ receive antenna of the MIMO radar system;
• estimating receiver response clutter correlation RYc as an estimated correlation;
• forming an optimum detector with said estimated correlation for said each receive signal among the plurality of receive signals;
• employing said optimum detector to estimate said target set of parameters from said each receive signal as an estimated target parameter;
• returning to said forming operation in response to said estimated target parameter exceeding an established tolerance;
• applying said estimated target parameter to the plurality of receive signals;
• and submitting said plurality of receive signals to the MIMO radar system.
