Range Density Function for Active Sensor Imaging

In this paper, a generalised target density function (TDF) is studied for active imaging by sensors such as radar. This is achieved by estimating a new TDF which is called range density function (RDF). It is proposed by utilising of a generalised range-angle density function for imaging. While the RDF is developed by a new approach based on inverse Wandermonde matrix computation, it is obtained by considering a new range and scanning angle plane different from the conventional methods.
