Abstract

The measurements for two targets will be merged when the targets are closely-spaced with respect to the resolution of the radar. Improved monopulse processing techniques for an electronically scanned array (ESA) can be used to compute a measurement for each target and used to update the state estimates. However, a substantial amount of radar resources is required to perform this operation. The integration of the ESA with additional sensors has the potential to enhance the tracking and reduce the resource allocation requirements of the ESA when targets are unresolved. A complementary sensor would provide measurements for both targets and can be employed to form a composite track for the ESA. The tracks will not be merged and the ESA can better utilize its resources. This paper presents algorithms for the tracking of maneuvering targets and multisensor integration for effective ESA resource management when tracking of maneuvering targets and multisensor integration for effective ESA resource management when tracking unresolved targets. The sensor suite includes an ESA and an IR Search and Track sensor. The effect of sensor integration on tracking performance and ESA resource allocation will be presented for single and multiple sensor configurations.
