Micro-integrated Design Of Guided Bullet Detection Guidance System

The paper makes a preliminary study on the semi-active guidance technology of the projectile,it is used to improve the hit precision when the small-calibre weapon against the long-range target.Guided projectile are generally used to attack the target within sight,Its trajectory is straight,and the laser semi-active guidance is used in the design.Considering the the limited space inside the projectile,The desgin should meet the technical requirements of low power consumption,high stability and high frequency response.According to the relevant indicators,the main components are analyzed and selected,the electrical schematic diagrams are designed and analysised,and also the microminiaturization designa bout the PCB diagrams are completed.The stability of the system is determined by simulation.The microminiaturized hardware PCB board integrates the detector signal acquisition and processing module,guidance control module,steering gear drive module and power supply module,which of the detection guidance system..And the working voltage about these hardware circuit modules of the detection guidance system is provided by a voltage source.The miniaturized design can meet the function of the detection guidance system..So the miniaturized design of the detection guidance system is realized.The design also involves a miniaturized optical system about the laser seeker with the high precision location capability for the Small laser semi-active guided projectile,it is on the birefringence principle of the lens to obtain high quality image of a ? 4 mm spot which on a four-quadrant detector with an effective area diameter of 5.33 mm using the ZEMAX optical software.And we can obtained the optical spot displacement diagram and energy diagram which in different fields of view.
