A method of implementing spread spectrum techniques in an automotive radar with wireless communication capabilities enables an anti-jammer radar capable of overcoming channel noise. The method is provided with a MIMO radar and at least one base station. The MIMO radar transmits the initial uplink signal and receives an ambient signal containing a reflected uplink signal and the downlink signal. The initial uplink signal is encrypted to overcome channel noise and jamming signals. The downlink signal is used to establish wireless communication between the base station and the MIMO radar. As such, the downlink signal is filtered and processed from the ambient signal. Similarly, the reflected downlink signal is also filtered from the ambient signal. Finally, the MIMO radar decrypts the reflected uplink signal to detect a plurality of targets and derive spatial positioning data for each target.
