New features have been added to SOPA:
- a square facet simulator using a cos^exp law to weight the effect of surfaces not facing the radar;
- the possibility to create maps of the estimated locations of the first returns for each frame;
- the possibility to create radargram-like images showing the minimum/maximum ground distance from the nadir point of the surface clutter contributions summing up in the simulations;
- plotting tools for quick visualization of all the main outputs of SOPA.
