Estimation of target position from a moving passive system using the differential Doppler method

The main focus of this work is on analysis of the Differential Doppler method having a designed algorithm for computing and 2-D visualization of the iso doppler curves for three-positional and two-positional moving stations with a stationary target. This work also describes the effect of the target position and velocity vectors of the moving stations on the shape of the iso doppler curves. Using the Differential Doppler method, new algorithm was proposed for determining the target position from two or three moving stations and for verifying its ambiguity in the Matlab program.
