Abstract

A test method for a method used for passively obtaining target data regarding a moving target, wherein bearing angles are measured as real target data from the bearing of the target using an on-board bearing system at successive path positions of a vehicle that determines its path positions using a compound navigation system, and distance, speed, course, and/or position of the target are determined therefrom. To verify this method, target and vehicle positions are measured using a GPS at the time the bearings of the target are taken. Target bearing angle and distances are calculated from the respectively associated positions of the vehicle and the target and are allocated to the path positions measured using compound navigation. A reference target path is estimated therefrom, and from associated pairs of values of the bearing angle and the target distance, and reference target data is derived therefrom and directly compared to the real target data.
