Abstract

A multi-static Doppler radar concept based on long-distance VHF frequency
recordings is presented and tested in a two-receiver, 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
multistatic configuration are tested in an off-line experiment over a
distance of 400 km. Aircraft position was recovered to an apparent
precision of 1500 m. The method also corrects for errors in time
synchronization between receivers.
