Lark-Wasp Guided Missile Seminar

Abstract

PURPOSE OF PROBLEM A-156R-S, LARK MISSILE CONTROL : The primary purpose of Problem A-156R -S, assigned by BuAer, is: "to modify the SP Shipborne radar and, with a radar beam control receiver, afford radar beam control of the Lark Missile." The Lark is a subsonic missile operating at approximately 0.85 Mach number. Two versions are under development: KAQ-1 Lark, designed and manufactured by the Fairchild Pilotless Plane Division; and KAY-1 Lark, designed and manufactured by Consolidated Vultee Aircraft Company. The specifications for the beam rider system provide that the operating range of the system shall be at least 90,000 yards; that the control shall be operable to at least 40,000 feet altitude. The target shall be considered to be comparable to a medium bomber. The SP Shipborne radar shall be modified to incorporate automatic tracking of the target and shall transmit control intelligence to the receiver in the Lark by pulse time modulation. The receiver shall be dimensioned as required to be located in the Lark; it shall accept and interpret the information received from the radar beam so as to furnish proportional control to the missile to maintain it on the line of sight between the radar and the target. PURPOSE OF PROBLEM O-126R-C, PROJECT WASP: The primary purpose of Problem O-126R-C assigned by BuOrd, is: "to develop and test a system for control of a guided missile by means of a radar beam modulated at different frequencies in different lobes." NRL PLANS FOR DEVELOPING BEAM RIDING GUIDANCE SYSTEMS: The problem of providing beam riding control for the Lark and developing the Wasp system of guidance are precisely similar in basic principle. The NRL plan for developing a beam riding guidance system has been based upon utilization of the implementation specified for control of the Lark missile.
