Integration of electronic support measures and an α-β radar tracker

In target environments that include electronic countermeasures, where the availability of radar range measurements is severely reduced, an integration of electronic support measures (ESM) into a multisensor tracker provides an inexpensive but effective approach to augmenting radar tracking systems. Tracking filter equations are presented for a multiheterogeneous-sensor tracking system consisting of radars and ESM sensors. Measurement time-based track updating is performed, due to nonperiodicity of ESM measurement acquisition times, instead of unusal track-based updates. Track updating using ESM measurements is accomplished via an EKF-based algorithm and radar measurements via an alpha-beta tracking algorithm. The integration of data from different sensor types is a logical response to increasingly hostile airborne threats. The technique described is a straightforward and cost-effective approach for accomplishing that integration.© (1990) COPYRIGHT SPIE--The International Society for Optical Engineering.
