Abstract : The patent describes a HF pulse doppler radar which eliminates the usual extent and direction ambiguities in velocity and acceleration measurements that are in excess of PRF/2. This is accomplished by preserving the complete spectral response obtained at IF for use in the signal processor and by circumventing the spectral folding which normally occurs in the product detector of the receiver and by counting the spectral responses in the upper and lower sidebands.
