1. A sensor system for measuring parameters used for guiding a gun-launched projectile, comprising:

  • a plurality of RF antennas mounted to the projectile, each RF antenna being arranged to receive an RF signal of a selected polarization; and

    a radar RF emitter/receiver system arranged to direct polarized RF signals toward the plurality of RF antennas mounted to the projectile, the radar RF emitter/receiver being further arranged to receive polarized RF signals backscattered from the plurality of RF antennas mounted to the projectile and process the received polarized backscattered RF signals to determine position and velocity vectors of the projectile.
