Since Radiometric methods are used to boresight the Haystack System, the Univac 490 antenna pointing system includes a radiometer data processing program which operates in real time concurrently with the antenna pointing programs. The main input to the program is comprised of 30-bit data words passed from the radiometric equipment to the computer via channel 5. Each word contains indentification bits allowing the computer program to distinguish between two different types of data auxiliary or radiometric. The processing of the auxiliary data consists of a simple check to determine if data associated with a particular identification falls within specified bounds for that identification. This data is then logged on the highspeed printer, along with its associated upper and lower limits, and an indication if the data is outside of the specified limits. Processing of the radiometer data is more complex in general, the primary output is a running measure of radiometric source temperature. The results of this processing are both logged and plotted on the high-speed printer in real time.
