Abstract:
A method of estimating a local plot density in a radar system observing an observation volume, the radar system configured to generate plots with plot attributes, by establishing a non-empty set of M-dimensional basis functions and corresponding coefficients, and repeatedly updating at least one coefficient based on at least one plot as obtained from the radar system, adjusting the basis functions and corresponding coefficients to represent a number of plots in a predetermined adjusting interval, and estimating the local plot density at a given point in the observation volume.
