Abstract: A system and method for measuring and predicting information on the position of approaching aircraft are disclosed. The system features a processor, an interrogating antenna, a receiving antenna, and a data link. The processor schedules interrogations and suppression pulses. Both of the antennas and the data link are in signal communication with the processor. The interrogating antenna transmits interrogations to a plurality of approaching aircraft. At least some of the interrogations include suppression pulses. The receiving antenna comprises at least three fixed, broad azimuth, array elements. The receiving antenna receives replies from each of the plurality of approaching aircraft and communicates the replies to the processor. The processor determines a state for each of the plurality of approaching aircraft based on the replies. The data link communicates information on the state of each of the plurality of approaching aircraft from the processor.

Abstract: A radar processor comprises a multi-port memory device having memory which can be accessed by at least three ports. A first port receives input data from a data providing means. A second port couples a first processor which performs radar processing. A third port couples at least one second processor which assists the first processor by also performing radar processing. The multi-port memory device further includes an arbiter for coordinating and determining when each of the three ports can access the memory of the multi-port memory device. The first and second processors share information with each other via the multi-port memory device.

Abstract: Representing weather data with elliptical or polygonal representations for transmission or reception. Ellipseticity may be determined, vertex coordinates may be shuffled, or polygons may be continuously fillable or filled based on filling flag values. Sides may be replaced within the polygonal representations. Certain storage requirements or transmission orders may be variable.
