Abstract: A combined algorithm for automatic target detection and height estimation, based on amplitude comparison using multipath lobes of three sensors positioned one above the other, and a three-positioned in a plane method, is proposed in this paper. A method for three-positioned radar system base estimation, allowing target height measurement with height probability of detection, is developed and applied. The measurement accuracies, achieved with two approaches for target height estimation with identical statistical and power detection parameters, are compared. The suggested approach can be successfully applied in different sensor system solutions.


Keywords: VHF height finding; sensor networks, simultaneous detection and estimation.
