Abstract
A radar antenna system comprises a plurality of transmitting sub-arrays; a plurality of receiving sub-arrays; and a transceiving control unit coupled to the plurality of transmitting sub-arrays and the plurality of receiving sub-arrays, configured to control the plurality of transmitting sub-arrays and the plurality of receiving sub-arrays, such that the radar antenna system selectively operates in one of an amplitude-comparison mono-pulse mode and a phase-comparison mono-pulse mode.
Claims10
A method, applied in a radar antenna system comprising a plurality of transmitting sub-arrays and a plurality of receiving sub-arrays, the method comprising:
- determining whether an angle of an object in relation to the radar antenna system is greater a specific value and control the plurality of transmitting sub-arrays and the plurality of receiving sub-arrays, such that the radar antenna system selectively operates in one of an amplitude-comparison mono-pulse mode and a phase-comparison mono-pulse mode;
- when the angle is greater than the specific value, controlling the plurality of transmitting sub-arrays and the plurality of receiving sub-arrays such that the radar antenna system operates in the phase-comparison mono-pulse mode;
- when the angle is smaller than the specific value, controlling the plurality of transmitting sub-arrays and the plurality of receiving sub-arrays such that the radar antenna system operates in the amplitude-comparison mono-pulse mode.
