1. An apparatus for wireless communication at a wireless device, comprising:
memory; and
one or more processors coupled to the memory and configured to cause the wireless device to:
transmit, for a first radar signal sensing that has a first range, a first radar signal that has a first chirp time and a first sweeping up time, wherein the first range is based on the first chirp time and the first sweeping up time;
measure wireless signals of a wireless communication environment, wherein the wireless communication environment includes the wireless device;
detect, based on the measured wireless signals, that a congestion level associated with the wireless communication environment exceeds a threshold congestion level;
decrease, based on the detected congestion level that exceeds the threshold congestion level, one or more parameters for a second radar signal sensing, wherein the one or more decreased parameters comprise at least a second sweeping up time that is shorter than the first sweeping up time and a second range that is smaller than the first range; and
transmit, for the second radar signal sensing, a second radar signal that has the first chirp time and the second sweeping up time.
