Abstract
The joint estimation problem of the scan rate and the position of a scanning emitter is investigated. The proposed approach takes advantage of the uniform rotating motion of the antenna main beam as it sweeps across a number of separate receivers. A joint estimator is developed based on a nonlinear least-squares (NLS) estimation. Several simulation examples are presented to compare the performance of the proposed estimator with the Cramer-Rao lower bound (CRLB).
