Abstract:

This paper dwells upon optimizing the azimuth sampling interval of digital surface maps used to model radar ground clutter. The resulting equations can be used to find the digital map sampling interval for the required calculation error and modeled power of the simulated signal, which determines the resulting distribution of backscatter intensity. The paper further showcases how the sampling interval could be increased by preprocessing the map.

Key words: ground clutter, mathematical modelling, radar, simulation
