1. A method for determining a state of health of an object detection fusion system, said method comprising: providing target data from a first object sensor and a second object sensor, where the target data from the object sensors is used by the fusion system to calculate fused object detection data; creating a context queue containing the target data from the object sensors, where the target data is arranged in sequential time frames which are stored in the context queue for a period of time defining a sliding time window; computing matching scores using the target data in the context queue; and calculating, using a microprocessor, the state of health of the fusion system based on the matching scores.
