Abstract : This invention relates to an FM-CW radar distance measuring system and a method for reducing the ambiguity and enhancing the accuracy in said system. The system disclosed utilizes three triangular wave modulators which modulate the RF output of the transmitter. The target return signal is mixed with a portion of the transmitted signal which has been delayed by an amount of time equal to the time required for a signal to travel to the target and return. This mixed signal is filtered to select the doppler component, and this component is amplified to utilize range information.
