Abstract

This paper presents experimental and simulation results from ongoing research on the influence of clutter on OTSDF filter performance. The degrading influence of overlapping clutter can be reduced by including colored noise in the filter construction or by tuning a white noise filter. Simulation results together with experimental results from a van derLugt correlator indicate that tuning of a white noise filter is the most effective for low levels of clutter in the input images whereas inclusion of colored noise is more effective for high levels of clutter. The experimental results are well in line with the simulations.
