Abstract :
Design and testing of the passive mm-wave sensor operating in 88-100 GHz range is reported. The scanning part of this sensor is based on a heterodyne configuration with a bandwidth up to 12 GHz and NF = 9-10 dB. It can receive like noise signals that are typical for passive mm-wave imaging. Depending on the antenna system the sensor can be configured for both in-door and out-door imaging conditions. Lab View interface matched with MatLab 7 data acquisition system has been designed and tested. Examples of in-door and out-door images reconstructed with this sensor are presented proving its applicability for homeland security needs.
