A Method of Single Observer Ranging Based on Double Bands of IRSTS

A method of single observer ranging based on double bands of IRST system is presented. The measurement model is established, on which it is given that the ranging formula and the formula of the velocity at the direction to the station of the target. The main advantage of the presented algorithm over those available methods of single observer ranging based on single band of IRST system is its not depending on the moving model of the target. Thus the presented algorithm removes their disadvantage of must assuming the moving model of the target. The results of the simulation of the computer verify the effective and the performance of the presented method.
