Successful demonstration of a video rate 94 GHz camera for concealed weapons detection has lead to interest in commercialization of this system. Besides the basic physics of object detection, there are many details a practical system needs to consider for the transition from experiment to product. We describe improvements in the RF modules, back end electronics, and user interface, along with additional video images captured with the improved system. RF module improvements include better low noise amplifiers and RF switches, along with a two-temperature calibration method resulting in a noticeable improvement in image quality. Analog electronics now have a more rapid offset correction, better stability, and better dynamic range. The user interface will now permit image fusion and other user- friendly features. Indoor experiments with active illumination are reported.
