Long-distance multistatic aircraft tracking with VHF frequency doppler effect (original) (raw)

IEEE Transactions on Aerospace and Electronic Systems, 2014

Abstract

ABSTRACT A multi-static Doppler radar concept based on long-distance VHF frequency recordings is presented and tested in a two receivers, one transmitter configuration. The core of the method is a mathematical model of Doppler shift generation in a passive configuration of many simultaneous transmitting radio stations and receivers that share the Doppler shift information they have recorded. The tracking capabilities of such a multi-static configuration are tested in an off-line experiment over a distance of 400km. Aircraft position was recovered to an apparent precision of 500m. The method also corrects for errors in time synchronization between receivers.
