Multi-target multi-platform sensor registration in geodetic coordinates

This paper describes a sensor registration methodology in a multi-unit and multi-target environment. Algorithms are presented for estimating multi-unit platform alignment biases in latitude, longitude and north angle. The main focus here is filtering and integration of sensor data from multiple units at distinct locations to produce accurate geodetic position estimates of these targets or threats. Analyses performed to assess target position error have shown this to be an effective method of obtaining a reliable geodetic position estimate in the environment of multi-unit radar tracking. Integrated target geodetic positions can be established via this method to support target designation and engagement in the multi-unit environments.
