1. A method that facilitates mitigation of radar interference, the method comprising:
performing object detection by a radar sensor system, wherein the performing of object detection includes generating and transmitting one or more object-detection (OD) chirps on an OD channel, which is one of a plurality of radar channels employed by the radar sensor system;
monitoring one or more unused radar channels for interference, wherein the unused radar channels include the plurality of the radar channels other than the OD channel, and wherein the monitoring of the one or more unused radar channels includes, in a sniffing mode, selecting a sniffing channel, which is one of the unused radar channels;
determining that at least one of the unused radar channels is free of interference; and
performing object detection by generating and transmitting one or more OD chirps on the determined interference-free channel.
