Patent ID: 8462041

Claim:
A device for the receiving secondary radar signals and for the quasi-dynamic or dynamic sectoring of a space to be monitored, which comprises: at least one antenna assembly (A) comprising N antenna elements (AE 1 , 2 , 3 , . . . , N) for the reception of transmitted secondary radar signals, a signal processing unit (SV) connected via a connection point (S) to the respective antenna elements (AE 1 , 2 , 3 , . . . , N) for the joint processing of all received antenna signals, said signal processing unit (SV) having a couple matrix (K) with adjustable coefficients (α 11 , α 12 , . . . , α 21 , α 22 . . . ) for sectoring of the space to be monitored and performing a superposition of the antenna signals by means of a multiplicative-additive combination of said received antenna signals, outputs associated with the couple matrix (K) for connection to individual receivers, and at least one receiver m ( 1 , 2 , . . . , M) connected to said couple matrix (K), wherein according to a dynamic sectoring of the space each receiver m (m = 1 , 2 , . . . , M) receives for each receipt telegram another weighted superposition of the antenna signals with certain couple coefficients (α 11 , α 12 , . . . , α 21 , α 22 . . . ), and whereby in the case of quasi-dynamic sectoring the adjustable coefficients (α 11 , α 12 , . . . , α 21 , α 22 . . . ) are fixed over a longer time period.
