In target environments that include Electronic Countermeasures (ECM), vhere the availability of radar range measurements is severely reduced, an integration of ESM into a multi-sensor tracker provides an inexpensive but effective approach to augmenting radar tracking systems. Tracking filter equations are presented for a multi heterogeneous-sensor tracking system consisting of radars and ESM sensors. Measurement time-based track updating is performed, due to non—periodicity of ESM measurement acquisition times, instead of usual track—based updates. Track updating using ESM measurements is accomplished via an EKF-based algorithm and radar measurements via an tracking algorithm. The integration of data from different sensor types is a logical response to increasingly hostile airborne threats. The technique described in this paper is a straight forward and costeffective approach for accomplishing that integration.
