Motion Modeling and Coordinate Systems

Array and target trajectory modeling, coordinate transformations, doppler shift

The Phased Array System Toolbox™ lets you model source, target, and jammer trajectories from initial positions and velocities. You can transform between coordinates systems, transform angular measurements, and convert between velocity and Doppler shift.
