with elimination of blind speeds

Full Title

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 > performing filtering on the whole spectrum without loss of range information, e.g. using delay line cancellers or comb filters > with elimination of blind speeds
