Key Signal Processing Technology and Development Direction of Loran-C Receiver
The performance of Loran-C receiver has a significant impact on navigation positioning and timing accuracy.The framework of Loran-C receiver is presented and some signal processing technologies are researched in this paper,such as signal ac-quisition,the sky-wave and ground-wave identification,cycle identification and the additional secondary factor correction,etc.The results shows that the currently theoretical methods always focus on a single problem and has some limits,while the whole re-ceived performance is to be verified in pratical application.Comparing to the research status of existing signal processing technolo-gies,the paper investigates the development direction of Loran-C receiver in our country from,the high dynamic signal acquisi-tion,the joint algorithm,nonlinear time-varying characteristics of the system and ASF data update.
