A mechanism for combining signals of multiple radars to achieve increased range, radar sensitivity and angle accuracy is provided. A first signal beam is radiated from an antenna of a first radar in the direction of a target. A second signal beam is radiated from an antenna of a second radar in the direction of the same target. The echo signals from the first signal beam and the second signal beam are received at both radars. The echo signals received at the first radar are processed to produce first radar processed echo signals and the echoes signals received at the second radar are processed to produce second radar processed echo signals. The first and second radar processed echo signals are combined to form an aggregate value.
L'invention concerne un mécanisme qui permet de combiner des signaux de radars multiples afin d'obtenir une portée, une sensibilité et une précision d'angle des radars accrues. Un premier faisceau signal est rayonné d'une antenne d'un premier radar en direction d'une cible. Un second faisceau signal est rayonné d'une antenne d'un second radar en direction de la même cible. Des signaux d'écho du premier faisceau signal et du second faisceau signal sont reçus au niveau des deux radars. Les signaux d'écho reçus au niveau du premier radar sont traités afin de produire de signaux d'écho traités du premier radar; et les signaux d'écho reçus au niveau du second radar sont traités afin de produire de signaux d'écho traités du second radar. Les signaux d'écho traités du premier radar et du second radar sont combinés pour constituer un valeur globale.
