The system includes an antenna composed of transmission sub-arrays (A1, ... A Q) illuminating one and the same zone of the space and at least one reception sub-array (A R), each sub-array having a given position in said array, each transmission sub-array transmitting a signal having a specific characteristic, the set of characteristics specific to each sub-array forming the simultaneous multiple transmission code, the detection of targets being performed by the transmission of a series of bursts of multiple transmissions, said series including at least two different transmission codes, echoes being detected in the main lobe and in the sidelobes, the system: - transmits different codes (67) from among at least two bursts, - detects the signals (68) originating from each direction; - carries out the aggregation (69) of the different signals (70) detected in each direction for said at least two bursts, said aggregation reducing the level of the echoes detected by said sidelobes. |
