Abstract
The present disclosure describes systems and techniques for estimating a height of an object by processing wave signals transmitted from a detection device to the object and reflected by the object. In aspects, a detection device transmits wave signals, which propagate via a direct path and an indirect path via reflection over a reflecting surface, to be reflected by the object. Operations include measuring wave signals reflected by the object and generating measurement vectors and producing a spectrum of an estimated elevation angle of the object over the range. Further, the operations include estimating the height of the object from the spectrum. The length of the window can be determined by estimating the range interval covered by a full phase cycle of a phase difference between the direct path and the indirect path from a current value of the range and a current estimate of the height of the object.
