Patent ID: 7002511

Claim:
A millimeter wave pulsed radar system comprising: a radar synthesizer comprising a voltage controlled oscillator/phase locked loop (VCO/PLL) circuit that outputs a fixed frequency signal, a direct digital synthesizer (DDS) circuit that generates in-phase and quadrature signals (I/Q signals), and a quadrature modulator circuit that receives the fixed frequency signal and I/Q signals and generates a signal operative as an intermediate frequency and local oscillator signal (IF/LO signal); and a radar transceiver operative with the radar synthesizer for receiving the IF/LO signal, and comprising a transmitter section having a frequency multiplier that multiplies the IF/LO signal up to a millimeter wave (MMW) radar signal, and a receiver section that receives a MMW radar signal, including a direct conversion mixer that receives the MMW radar signal and the IF/LO signal to produce I/Q baseband signals that are later digitized and processed.
