i have a question about your decline algorithm.
result=1/this.getDistance(x,y,i) * Math.sqrt((rField/(4 * Math.PI)) *
scatterPoint[i].getValue());
result=result / scatterPoint[i].getValue();
how should this work? if this derived from the surface area of a
sphere, then should this be not decline = rField / ( distance^2 * 4 *
Pi ). why did you take the square root?
and what about correction to dbm?
