Radar Echoing Area is (REA) and is also known as the Radar Cross Section (RCS). It's not quite the same thing as the radar visibility range. RCS is a property of the target, and varies with the target aspect w.r.t. the radar, and also the radar frequency. Radar visibility range is a function of the RCS and the power density of the radar at the target. Depending on the level of realism you want for radar, we either need a crude visibility range as a property of the target, or the RCS (probably an estimate) and have the radar work out if the target is visible, taking into account the RCS and the radar horizon.
