Abstract


Laser phased array radar is a new radar system , the application of optical phased array technology makes the mechanical structure of the laser radar system is simpler , lighter weight , and has a good overall performance . LCD phased array has the advantages of low drive voltage , low power consumption , fast response , LCD phased array laser deflection can effectively solve the laser beam control radar high performance and excellent operational flexibility . Therefore, in recent years , liquid crystal phased array technology to get a more in-depth study ( and applications ) has become one of the important trends in optical phased array , with the liquid crystal material . In wave controller is one of the key technologies of liquid crystal phased array . This thesis is based on specific research projects , carried out for liquid crystal laser radar phased array beam controller work as follows : 1 ) analysis of the the wave the controller functional requirements proposed the two waves controller hardware system design , and then the two programs the comparative analysis of the selected final design of the the wave controller module hardware circuit and draw the PCB . 2 ) according to the present stage wave controller is mainly used for the actual situation of the the deflection waveform control test trials , the development of the control software used for the the wave control test test . 3) analysis of the liquid crystal phased array wave control principle and method , using the function to simulate the properties of liquid crystal curve design deflection waveform control test data generation algorithm , using this algorithm to generate the waveform control test data for the deflection waveform control test trials . 4) of each module debug the wave controller hardware system to verify the work properly , and finished wave controller structures the wave control test test platform , and carried out a series of waveform control test trial . The test results show that : the wave controller to achieve the basic functionality of the design requirements of the the wave controller capable of laser programmable electrically controlled deflection control . Our group developed liquid crystal phased array scanning components with wave control capabilities, deflection of the laser scanning can be achieved .
