A New Analysis of the Multipath Radar Data Measured by Standard Telecommunication Laboratories

Presented is a new analysis of some multipath radar data measured with an array antenna and low-flying aircraft by Standard Telecommunication Laboratories (STL) Ltd. The data have previously been analyzed with the singular value decomposition (SVD) method by Haykin, Greenlay, and Litva. These authors were mainly interested in whether or not the' SVD method produced elevation estimates consistently close to the true target elevations derived from an adjacent optical tracker. The new analysis, also using the SVD method, has produced additional results. Firstly, it demonstrates a practical technique for selecting target elevation estimates when the target range was less than 6.5 km. Secondly, it provides an explanation, supported with simulations, for the presence of many false tracks branching out from the target and image tracks.
