Abstract:
The so ftwa re designed in th is pape r is used to ca librate the po inting accuracy of the w eather radar antenna, and is app licab le to the radar w ith h igh prec ision in an tenna pos itioning. Th is m ethod takes the sun as the re ference object. The tim e o f ca libra ting is sho rtened in tw ow ays. The scann ing scope o f the weather radar is narrow ed by setting the location of the rada r antennaw ith theoretical pos ition o f the sun prev iously to shorten the search ing time. The rea-l tim e data transm iss ion betw een radar front-end system and the so ftw are is accomp lished by us ing UDP m ulticast m ode and mu ltith reading mechan ism. The so ftwa re is developed in Eclipse IDE w ith Q t based on the L inux OS. The test results showed that the so ftw are m eets the expected requ irem ents. It can search the sun no ise signal autom atically.
