Abstract
A radiometric data acquisition and display system is provided. The system has a detector assembly with a boom. A radiometer is connected at an end of the boom. The radiometer has a sensor head including an antenna horn to acquire radiometric data from an area of interest. A rangefinder is constructed and arranged to provide location data indicative of a position of the sensor head, and a data processor is connected to receive the location data from the rangefinder and the radiometric data from the radiometer. The data processor includes signal processing circuitry and a display connected to the computer. A method of acquiring and displaying a radiometric image of an object is also provided. The method has the steps of: randomly sweeping a radiometer detector over an area of interest; detecting an object in a portion of the area of interest; sweeping the radiometer detector over the object to acquire radiometric image data; processing the data to construct an image from the radiometric image data; and displaying the image. In an embodiment, the method distributes the radiometric data over an antenna pattern to construct an image using the location data.
