Patent number: 10476152Abstract: A method and system which enable the automatic adjustment of the rotational speed of a radar antenna in a radar system having a continuously rotating radar antenna based on where objects are being detected. The automatic adjustment of the rotational speed of the radar antenna is controlled by a controller integrated with the radar system and is based on the bearing of the emitting antenna relative to objects being detected. The method relies on continuously reading the angular position of the antenna and corresponding the presence of detected objects to this angular position so as to automatically adjust the speed of the antenna to slow down the antenna while it is directing wave signals towards detected targets and speed up the antenna while it is directing wave signals in a direction where there are no detected objects.Type: GrantFiled: December 15, 2017Date of Patent: November 12, 2019Assignee: United States of America as represented by Secretary of the NavyInventors: Jacoby Larson, Darren Powell
