Does the radar automatically correct for the angle?

JoeBloe is ignorant ;-)


What I should be ignoring is retarded posts like this one that makes
claims, yet provides zero backing for them.

Tell us, oh guru of RF emissions, what error is introduced in a test
result of 60 MPH with a car moving at 60 MPH.

At one degree angle of incidence:

At ten degrees:

At 45 degrees:

At 90 degrees:

The pulse goes out at the speed of light (nearly) and is actually a
serial train of pulses. Several pulse trains are sent during a single
test, and the doppler electronics inside the gun perform the
deterministic result.

So tell us, ***... What amount of error can we expect to see
for sub 100 MPH cars?

What amount of error would we expect to see for mach speed jets
passing into the field of sensitivity for the device?

Can't answer those questions? Then *** off, ***.
