1. A radio detection and ranging (radar) system, comprising:
a first plurality of antennas configured to receive a first radio wave in an operating beamwidth of the radar system, wherein the operating beamwidth is divided into a plurality of sectors; and
a controller that is coupled to the first plurality of antennas, and configured to:
determine a direction-of-arrival and a power level of the first radio wave;
determine, based on the direction-of-arrival and the power level of the first radio wave, a power level of received signal energy within each sector of the plurality of sectors;
select, from the plurality of sectors, a first set of sectors such that a power level of received signal energy within each sector of the first set of sectors is less than a threshold value of the corresponding sector, wherein the first set of sectors includes fewer than all of the plurality of sectors; and
broadcast a second radio wave within only the first set of sectors.
