MATLAB激光引信中的测距及抗干扰技术研究

摘要引信是防空反导的重要技术，传统引信有机电触发引信、静电引信等，激光引信相对传统引信有非接触、动态、精确度高的优势。激光引信是近程、动态的测距技术。本文比较了目前常见的几种激光测距法：干涉法、脉冲法、相位法以及三角测距法，考虑到近程、动态的要求，激光三角测距法所具有的特点能够满足，随后本文论述了其满足测距量程和精度的可靠性，进一步研究了合理的系统结构、参数设置、光敏单元器件与激光三角测距的重要关系。81417

Title Research on ranging and anti jamming technology in Laser Fuze

Abstract Fuze is an important air defense and missile defense technology。The traditional fuze includes organic fuze, static electricity fuze, etc。Laser fuze has the advantage of non-contact, dynamic and high accuracy compared to the traditional fuze。

Laser fuze is a short-range, dynamic ranging technology。Several kinds of laser ranging method such as interferometry,pulse method,the phase method and triangulation method are compared in this paper。Considering the requirements of short-range and dynamic,the laser triangulation method is choosed because of it's characteristic。And then the reliability of the measuring range and accuracy was discussed in this paper。And the important relationship between the laser triangulation and reasonable system structure,parameter setting, photosensitive unit is futher studied。

There will be subject to all kinds of interference in the working process of laser fuze,and the jamming and anti-jamming technology is studied in detial in this paper,and the study of the random disturbance is focuses on。For its characteristics of uncertainty and strong effect,the method of continuous determination is given,the decision process is designed,the simulation program is compiled。Finally,the feasibility of the scheme is verified by using MATLAB simulation。
