Open the CIPO recordAbstract From the Canadian patent
A method wherein the scan rate of an active emitter is simultaneously estimated by a tracking receiver and a radar system and are then compared to correlate tracks generated by the tracking receiver and the radar system. The output produced by the present method provides for data that is more accurately indicative of the locations and identifications of emitters tracked by the tracking receiver and the radar system. More specifically, the method comprises the following steps. An active emitter having a scanning antenna is simultaneously tracked using a tracking receiver and a radar system.

Why it's free to use
- Filed May 15, 1997 and granted November 23, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended May 15, 2017.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by May 15, 2019.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
