Abstract:
A 35 GHz alternating current (AC) direct detection receiver for passive imaging has been studied and presented. The Monolithic Microwave Integrated Circuits (MMIC) Low Noise Amplifiers (LNAs) with high gain and wide band are cascaded to provide enough gain for high sensitivity in the receiver. On basic of discussing the structure and mechanical chopping modulation, the signal model and compensation mechanism is emphatically analyzed. Finally, the imaging result is given.
