G01S13/5244 - CPC Classification

Classification description:

Systems using the reflection or reradiation of radio waves, e.g. radar systems; Analogous systems using reflection or reradiation of waves whose nature or wavelength is irrelevant or unspecified; Systems using reflection of radio waves, e.g. primary radar systems; Analogous systems; Systems of measurement based on relative movement of target; Discriminating between fixed and moving objects or between objects moving at different speeds using transmissions of interrupted pulse modulated waves based upon the phase or frequency shift resulting from movement of objects, with reference to the transmitted signals, e.g. coherent MTi Adaptive clutter cancellation
