Phased array radar with monopulse algorithm measurement

A radar apparatus for identifying targets in an environment comprising:

• a phased array radar transmitter, operable to generate and transmit a plurality of transmit beams into the environment;
• a first phased array radar receiver configured in a receiver arrangement and operable to receive a plurality of first receive beams from the targets, the first receive beams having a first beam detectable area;
• a second phased array radar receiver configured in the receiver arrangement and operable to receive a plurality of second receive beams from the targets, the second receive beams having a second beam detectable area;
• and
• a radar controller having an electronic control unit, the radar controller operable to steer the plurality of transmit beams, the first receive beams, and the second receive beams,
• the radar controller using the plurality of first and second receive beams to calculate a weighted target angle histogram, a complex amplitude monopulse ratio, and identify angle information of the targets within both the first and second beam detectable areas.

A method for controlling a radar apparatus for detecting targets in an environment comprising:

• providing a phased array radar transmitter, operable to generate and transmit a transmit beam into the environment;
• providing a first phased array radar receiver configured in a receiver arrangement and operable to receive a first receive beam having a first beam detectable area;
• providing a second phased array radar receiver configured in the receiver arrangement and operable to receive a second receive beam having a second beam detectable area;
• and
• providing a radar controller having an electronic control unit, the radar controller operable to steer the transmit beam, the first receive beam, and the second receive beam,
• calculating, by the radar controller, an amplitude monopulse ratio using the first and second receive beams,
• calculating, by the radar controller, angle information of the targets within both the first and second beam detectable areas using the amplitude monopulse ratio.
