The Grove (BGT24LTR11) max detection speed & distance

Having looked at the speed & direction detection demo

I was wondering what is the max speed it can detect at different distances eg. at 1m?
Is there a way to limit/filter the noise from objects beyond certain distance by software?
Will it detect an arrow or bullet in size e.g.5x5x10mm & speed 300m/s +?

Many thanks in advance.

Anyone here to support with techcal capabilities of the component?
