Without computer controls, it's kind of crap shoot on what you're going get with the return signal.

The SJ radar used a very rudimentary magnatron for the output. The Brits invented the magnatron in the mid-thirties. The SJ set operated in the 2cm (4 Ghz) which is much better than the German sets which operated from 200-600 Mhz. Microwave is highly focused with very low dispersion. It was very high tech for it's day.
I think the radar model, which was tweeked by CapnScurvy is pretty close to real life.

I worked on fire control and navigation radar for the A-6 and F-4 in the Marines.

so, the SJ performance that i experienced is normal for WWII?

i thought that radar could perform regardless of the weather, even in WWII.
