Extraction of height information from target shadow for applications in ATC

Physical attributes, e.g. length and width of a target can be extracted from its radar signature for target characterization. However, an additional dimension, i.e. height can provide value added information to distinguish between targets, e.g. between tanks and APCs, which may have similar lengths and widths and which exhibit similar intensity characteristics. For a non-interferometric data collection system, the height of a target can be accurately extracted from its shadow at low grazing angles, fine resolution and a cluttered background
