  • Method and apparatus for synthesizing multi-channel radar or sonar data
    Patent number: 6069582
    Abstract: Synthesized multi-channel data is provided based on real world single channel data, thereby yielding data with high fidelity that can be used to test multi-channel equipment and processing techniques. Simulated data representing time dependent characteristics of moving targets can be integrated with the synthesized multi-channel data. In one embodiment a multi-channel data generator (20) includes a real radar data module (30), a computer simulated radar data module (40) and a composite radar data module (50). The real radar data module (30) generates synthesized multi-channel background data (38) based on real world single channel radar data (32). The computer simulated radar data module (40) includes a temporal signal model (42) and a radar signal simulator (44) for generating multi-channel time dependent data (46).
