A guidance system for guiding each of several projectiles toward a moving
target has a platform having a radar system for illuminating the target
with a radar signal. Each projectile has a receiver for receiving the
radar signal reflected from the target, a transponder for replying to
Global Positioning System (GPS) like timing signals from several timing
signal sources, and a data link transceiver for establishing a
bidirectional data link to the platform. The data link carries the
measured frequency shift of the radar signal reflected from the target as
measured by the projectile. A computer on the platform computes a
relative position of each projectile with respect to the target from
tracking the moving target using the radar system and the reply signal
from the transponder on each projectile. The data link sends guidance
commands from the platform to each projectile to guide the projectile to
the target.
