Abstract
A modular radar system using both FM/CW and pulse waveforms for automotive collision avoidance applications. The radar system comprises a transmit and a receive antenna for transmitting and receiving, respectively, either one of FM/CW waveform and pulse waveform, a voltage-controlled oscillator (VCO) for generating a pre-set waveform for the transmit antenna, a modulator for modulating the pre-set waveform of the VCO, a switch for allowing the pre-set waveform from the VCO to be transmitted for a predetermined interval so as to generate the pulse waveform, a timing generator for causing the modulator to execute through a pre-set sequence of frequencies for either one of the pulse and FM/CW modes of waveforms with the timing generator controlling the transmission of one of the FM/CW waveform and pulse waveform, a balanced mixer for signal conversion In both FM/CW and pulse modes, an IF/Baseband receiver for amplifying the received FM/CW waveform and for IF-amplifying the received pulse waveform to generate an in-phase and a quadrature baseband output, a coherent oscillator for generating a coherent oscillating signal of a predetermined frequency to the receiver for centering the IF-…
