Abstract


Azimuth measurement is large radar equipment , and various navigation systems as well as the control system senses an important way of their own state , azimuth measurement system is of great significance . The rotational angle of the radar azimuth axis radar signal is transmitted to the terminal, comprising the angular signal at the transfer of the mechanical structure , selsyn angle signal converted into an analog signal, the axis angle converter for analog to digital conversion and other processes , the converted digital signal after the final sent to the radar terminal . In the various processes in the signal conversion , there is a certain degree of accuracy error . Radar error theory based on the mathematical model of the to based selsyn the radar azimuth measurement system to analyze the causes of error of angle measurement system and typical aspects ; issues combined with the typical coordinate radar , for selsyn the installation of the machine , based on the accuracy of the experiment data , proposed a method to improve the measurement accuracy of the radar azimuth dual-channel combination method , provided the design basis for product design . Finally, the topic ADAMS dynamic simulation of a certain type of radar antenna turntable system dynamic simulation software . Curve based on a variety of dynamic simulation output , performance , range of motion of the mechanical system , collision detection , and peak load can be predicted , optimal design , you can also find out the reason for the actual work to improve .
