locking

Let me clarify this.

New abs systems work at around 20hz. Extra zero, sorry.

I mean when you are reducing your average velocity down to psl you need to do it at a resonable rate to prevent accidents. At that rate your instantaneous velocity will not be changing fast enough and the radar will lock your speed by getting a relatively constant reading over a short period of time.

Instead of slowing down by reducing your average velocity through a relatively slow decrease in instantaneous velocity over time, you slow down by using sudden acceleration and sudden braking. This creates a vibration, sort of like a decreasing sharp sawtooth function. Your average velocity will be decreasing but the relative instanteous velocity would be constantly fluctuating at at a high rate. The radar will see its readings jump all over the place over its sampling period and will not lock.

I'm pretty sure newer radar guns are too smart for anything like this.

A "smart" radar should reject odd signals.
