Abstract

Over-the-horizon-Radars (OTHRs) operate in the High Frequency band (3 to 30 MHz); they are able to detect targets beyond the horizon and are employed in many applications such as scientific meteorological studies, surveillance and oceanic platform control. The radar operates for long periods of time without interruption, this requires analyzing the echo signal during the time of operation. In this article an adaptation of Mallat's algorithm is proposed; the method compute the wavelet's coefficients of consecutive intervals of the signal in a multiresolution analysis framework. The coefficients are calculated and used efficiently to estimate the radial velocity of the target over the time.
