Abstract

This paper first briefly describes the Laser Detection and Reciprocal Targeting (LDART) system being developed under the DARPA NEST program, whose purpose is to detect and locate enemy target designators. The system's sensor is an array of microelectronic (MEMS) detectors, each of which can measure the directional angle of incident light with a random error, whose distribution is known. The detector errors cause the sensor to perceive the source as if in a location that is generally different from its actual location. The paper's main contribution is to show how to optimally estimate the actual laser source location. We derive the probability distribution of perceived locations and show how it depends on both the source and sensor parameters. The distribution is then used to develop the maximum likelihood estimator of the actual source location, which allows to pinpoint the source with very good precision in spite of noisy measurements furnished by individual detectors.
