Abstract: A system includes a controller that includes a processor and a memory. The processor executes computer-executable instructions stored in the memory to operate the controller. The instructions cause the controller to determine at least two beam patterns for separate transmit beams that operate within the field of regard to be scanned by a Radio Detection and Ranging (RADAR) beam generator. The instructions also cause the controller to generate beam pattern commands to the RADAR beam generator to generate the beam patterns. The beam pattern commands specify a pointing direction for each of the separate transmit beams that operate within each portion of the field of regard.

Abstract: A system includes a controller having a processor and a memory. The processor executes computer-executable instructions stored in the memory to operate the controller. The instructions cause the controller to determine at least two beam patterns for separate scanning receive beams that operate within a field of regard to be scanned by a Radio Detection and Ranging (RADAR). The instructions cause the controller to generate beam pattern commands to form the separate scanning receive beams based on the determined beam patterns, the beam pattern commands specify an azimuth beamwidth and a pointing direction for each of the separate scanning receive beams that operate within each portion of the field of regard.

Abstract: An apparatus for attenuating vibration transmission between first and second structures includes a rod extending entirely through, and being mechanically connected to, both of the first and second structures. The rod defines a central longitudinal axis. A piezoelectric sensor senses vibrations in at least one of the first and second structures and responsively generates a voltage. The piezoelectric sensor is disposed entirely longitudinally between the first and second structures. A piezoelectric actuator actively attenuates the vibrations sensed by the piezoelectric sensor. The piezoelectric actuator is at least partially driven responsive to voltage generated by the piezoelectric sensor. The piezoelectric actuator is disposed entirely longitudinally between the first and second structures. At least one of the piezoelectric sensor and the piezoelectric actuator has a throughhole through which the rod entirely extends.
