An alternate method for measuring the radar cross section (RCS) of objects without relying on expensive anechoic chambers to eliminate reflections from foreign objects is proposed. In traditional radar systems, reflections from stationary objects or clutter can indeed interfere with the desired signal. The distinguishing method is based on the well-established principle of moving targets indication (MTI). By exploiting the Doppler shift we are able to filter out reflections from stationary objects, which can significantly improve the accuracy of RCS measurements, which makes it possible to effectively extract a useful signal from a uniformly moving target under test. Reflections from stationary objects can be eliminated if we place the measured object on a uniformly moving at a certain speed platform. The use of higher-order MTI filters allows for even better clutter suppression, in environments with multiple stationary objects are present.
