För att mätningarna skall bli bra utnyttjar man en metod (dopplereffekten), den gör så att man väljer endast rörliga föremål. Om man inte använder sig av denna metod kan man få med reflektioner från berg och skog. Radar Doppler Shift vs Speed Ground echo clutter is usually the strongest signal reflection, but because the ground is not moving it is does not have a Doppler shift.

micro-Doppler features, and 4) micro-Doppler effect in radar is demonstrated using real radar data. In Section II, we develop a model for analyzing the micro-Doppler effect. In Section III, we briefly introduce high-resolution time-frequency transforms for analyzing time-varying frequency spectrum. In Section IV, we apply the model for analyzing
When, in addition to the constant Doppler frequency shift induced by the bulk motion of a radar target, the target or any structure on the target undergoes micro-motion dynamics, such as mechanical vibrations or rotations, the micro-motion dynamics induce Doppler modulations on the returned signal, referred to as the micro-Doppler effect. Doppler radar sends the energy in pules and listens for any returned signal. The phase shift effect is similar to the "Doppler shift" observed with sound waves. With the "Doppler shift", the sound pitch of an object moving toward your location is higher due to compression (a change in the phase) of sound waves.

18 aug. 2009 — Radarn utnyttjar dopplereffekten, samma princip som polisen länge använt för att fånga fartsyndare. En radiosignal på 10 gigahertz sänds ut
This also makes intuitive sense: If you want to estimate the velocity of a target, you need to probe it longer - aka - you need to send out more pulses - aka - more data, and thus, a larger record length.
