U.S. Patent 8,373,591 System For Sensing Aircraft and Other Objects - $157,700 - (Reno, NV)
For Sale- U.S. Patent 8,373,591 System For Sensing Aircraft and OtherObjects issued February 12, 2013. Patent Term Adjustment is 243 days. AbstractA system for sensing aircraft and other objects uses bistatic radar with spread-spectrum signals transmitted from remotely located sources such as aircraft flying at very high altitudes or from a satellite constellation. A bistatic spread spectrum radar system using a satellite constellation can be integrated with a communications system and/or with a system using long baseline radar interferometry to validate the digital terrain elevation database. The reliability and safety of TCAS and ADS-B are improved by using the signals transmitted from a TCAS or ADS-B unit as a radar transmitter with a receiver used to receive reflections. Aircraft and other objects using spread spectrum radar are detected by using two separate receiving systems. Cross-Correlation between the outputs of the two receiving systems reveals whether a noise signal is produced by the receiving systems themselves or is coming from the outside. The Examiner required a restriction of the application and Icomplied.The ‘591 patent teaches the use of a satellite constellation to transmit encrypted signals that are used in a bistatic radar system that allows an aircraft to detect other aircraft and other objects. The satellite constellation can also be used for communications,a backup for GPS, and for long baseline interferometry to validate the digital terrain elevation database. This patent application was published 7/14/2011 which might be long enough ago for someone to put it in one of the satellite constellations now being launched. Do I have any evidence that someone is using my patent? No. If they are I doubt they would make that information public.
