Abstract

An artillery shell radar system is disclosed including an antenna directed off axis to produce, in conjunction with the spin of the artillery shell, a conical scan of the target area, with the off axis angle being adjustable by changing the phase shift used in a phased array. Radiation reflected from the target after transmission by a transmitter within the artillery shell is processed to detect and select a target whose position is used to guide the artillery shell by adjustment of guide fins. Gyroscopic inertial navigation equipment and ECM detection may be included.
