Abstract
The invention is a radar system using sum and difference signals for tracking targets, wherein the system includes aperture means having a cross sectional area for transmitting energy toward a target and receiving return energy; and circuit means for generating sum and difference signals, the circuit means being selectively coupled to said aperture means, with the sum signal being generated using energy from the entire aperture means and with the difference signals being generated using return energy from the aperture means exclusive of energy from a predetermined area. The invention permits simultaneous optimization of the sum and difference signals and also suppresses the near-in sidelobes in the difference signals.
