Passive radar system

MEASUREMENT OF COORDINATES OF UNMANNED AERIAL VEHICLE RADIO BEАCON

An experimental system for measuring the parameters of the flight trajectory of its own object-radio beacon, in particular, in the unmanned aerial vehicle (UAV) is developed and tested. Passive radio-location system is used. The difference-phase, difference-time and difference-frequency methods are compared. The first one provides the sufficient precision, not more than 1 deg. in the range of 30 to 140 deg. The phase measuring device is based on chip AD8302, operating at the frequency range up to 2.7 GHz.
