Simulations for Evaluation of Sensor Systems Exposed to Countermeasures

A methodology for simulation of multi-sensor systems exposed to countermeasures has been developed with the aim to investigate how multi-sensor systems are affected by different types of countermeasures and deployment tactics. The target recognition function of a combined radar/IR-seeker exposed to countermeasures is studied. Features extracted from simulated high range resolution radar data and IR images are fused. Sensor data are simulated for a seeker approaching ground vehicle targets moving on a grass field. The countermeasures consist of IR and radar attenuating smoke. The rate of correct classification is always higher for fused sensor data than for a single sensor as long as the proper confidence level of the data is considered
