Abstract: Radar system using sum and difference signals for tracking targets, wherein the system includes aperture means (10) 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 (H, I, J, K). The invention permits simultaneous optimization of the sum and difference signals and also suppresses the near-in sidelobes in the difference signals.

Abstract: Un système radar utilisant des signaux d'addition et de soustraction pour la poursuite de cibles comprend des moyens d'ouverture (10) ayant une zone de section transversale pour la transmission d'énergie vers une cible et pour la réception d'une énergie de retour, et des moyens de circuit pour générer des signaux d'addition et de soustraction, ces moyens de circuit étant couplés sélectivement aux moyens d'ouverture. Le signal d'addition est généré en utilisant l'énergie provenant des moyens d'ouverture totale, et les signaux de soustraction étant générés en utilisant l'énergie de retour provenant des moyens d'ouverture à l'exclusion de l'énergie provenant d'une zone prédéterminée (H, I, J, K). L'invention permet l'optimalisation simultanée des signaux d'addition et de soustraction et permet également la suppression des lobes latéraux voisins dans les signaux de soustraction.
