US Patent 7940208 Optically-augmented microwave imaging system and method

An image processor includes an optical processor and a microwave processor. The optical processor is configured to extract optical image information from optical image data provided by a sensor, the optical image data representing an optical image of an object. The microwave image processor is configured to produce microwave image data representing a microwave image of the object in response to the extracted optical image information and microwave measurements provided by a microwave imager based on illuminating the object with microwave radiation.
