Comparative Description of Setups for MMW-Imaging of Persons

For the purpose of MMW-imaging different setups can be considered. When active sensorics are applied the synthetic aperture radar (SAR) concept is often used, since real apertures would require large dimensions in order to obtain the required resolutions. The resulting images show different characteristics, depending on shape and position of the synthetic aperture. Imaging results obtained with different configurations are compared. A method of comparing different setups is presented in the following.
