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). The composite radar data module (50) receives the synthesized multi-channel background data (38) and the simulated time-dependent data (46) and integrates this data (38 and 46) together with application specific signal modification data (52) to generate composite data (54) with realistic background data and time-dependent characteristics.
