Programmed Doppler Radar Tracking Module Design And Control System

This thesis according to the velocity measurement principle of Doppler radar, has analysed the mathematic model and handling method adopted by velocity measurement data processing of common ball Doppler radar. Specifically for Base-bleed projectile, has analysed its trajectory characteristic, based on which we suggest a programmed track method for Base-bleed projectile, and analyse the mathematic model.Then, respectively adopt Common ball Programmed track method and Base-bleed projectile Programmed track method to track Base-bleed projectile. By analyzing the result wo know the latter one's function is far higher than the former.For having amicable and handling convenient interface, the module having be carried out, which is applied to the Programmed track Doppler radar.On the grounds of Doppler radar servo control principle, two-phase hybrid stepping motor's control system is studied. This thesis adopts 86HS35 two-phase hybrid stepping motor as controlling electromotor, have analysed whose operating principle, and analyse its dynamic capability by simulating, and we educe that the system has good dynamic response and following. To drive the two-phase hybrid stepping motor, we adopt constant frequency pulse and subdivides drive circuit with M535, which with low speed vibration and precision orientation. The main control cell adopt LPC936 singlechip, which offers the control signal.
