Target Kinematic State Estimation With Passive Multistatic Radar

This article examines methods for and results of determining the instantaneous kinematic state a target, i.e., its velocity heading, using passive multistatic radar. is achieved by combining bistatic target range Doppler information obtained multiple transmitter-receiver pairs, to estimate appropriate vector. estimation provided as set closed-form equations, derived general case applicable an arbitrary number transmitters. The feasibility proposed approach accuracy predictions, function transmitters, are experimentally confirmed via dedicated experimental campaign with Global Navigation Satellite Systems transmitters opportunity, where two different relatively slow-moving maritime targets were in field view up 12 satellite belonging constellations (GPS, GLONASS, Galileo) simultaneously.
