% Computes the radar signal to noise ratio for a pulsed monostatic radar.
Losses are positive dB. A loss of 10 would be 10 dB.
If aTarg is not [] it will compute sigma. Otherwise sigma will be
used. sN, pR and PN will be a vectors if d.r is a vector. eRP is a
scalars.
Type RadarSN for a demo of an L band radar from the reference.
