A system for measuring radiant signals includes a detector circuit for detecting a time multiplexed, measured radiant signal and reference signal. A switch is connected to the detector circuit for receiving signals from the detector circuit. A measured signal sampling circuit, a reference signal sampling circuit, a measured alias circuit and a reference alias circuit are connected to the switch, which is operative for switching among the sampling and alias circuits to remove sampling noise and improve switching latency.

Switched measuring system and method for measuring radiant signals

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