SOFTWARE DEFINED AUTOMOTIVE RADAR
First Claim
1. A radar sensing system for a vehicle, the radar sensing system comprising:
- a plurality of transmitters configured for installation and use on a vehicle, wherein the transmitters are configured to transmit modulated radio signals;
a plurality of receivers configured for installation and use on the vehicle, wherein the receivers are configured to receive radio signals, wherein the received radio signals are transmitted radio signals reflected from an object in the environment;
wherein each transmitter of the plurality of transmitters comprises a digital processing unit, a digital-to-analog converter, an analog processing unit, and transmitting antennas;
wherein each receiver of the plurality of receivers comprises a receiving antenna, an analog processing unit, an analog-to-digital converter, and a digital processing unit; and
a control unit configured to individually modify one or more operational parameters of one or more transmitters of the plurality of transmitters and one or more receivers of the plurality of receivers, wherein the control unit is configured to dynamically modify one or more operational parameters of transmitters and receivers, based upon changing environmental and situational conditions.

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.
