HEAD ON STATE GUIDE FOR HIGH SPEED TARGET

摘要

PROBLEM TO BE SOLVED: To provide a system for guiding a projectile by calculating an acceleration command such that the angle of gaze approaches 0 using the information of the seeker swing angle, the lateral speed, and acceleration of the projectile. ;SOLUTION: The head on state guide comprises an inertial unit 1 for detecting the speed and acceleration of a projectile, a seeker 2 for detecting the gaze angular speed ω, the seeker swing angle λ, the relative speed Vc the relative distance R, an operating unit 3 comprising a head on guide rule operating unit 20 and a proportional navigation operating unit 24, and a controller 4 for a steering wing 5. The head on guide rule operating unit 20 comprises operating units 21, 22, 23, the proportional navigation operating unit 24 outputs an acceleration command ε based on the proportional navigation, the operating unit 21 outputs an acceleration command δ1 based on the seeker wing angle λ, the operating unit 22 outputs an acceleration command δ2 based on the lateral speed v, and the operating unit 23 outputs an acceleration command δ3 based on the lateral acceleration n.;COPYRIGHT: (C)1998,JPO
