The absolute calibration of hydrophones using the planar scanning technique in the frequency range 0, 5 mhzto 15 mhz
用0 . 5mhz 15mhz頻率的水平掃描技術對水下擴音器進行的絕對校準In recent years, radio technology has developed very quickly in our country. however, a radio monitoring receiver with broad frequency scale ( 20 - 3000 mhz ), high scanning rate ( above 1ghz / s ) and whole spectrum real - time display has not developed. some imported monitoring receivers with broad frequency scale can only scan slowly and could n ' t meet actual needs. not only these imported receivers " price is high but also those developed countries usually limit the quantities of imported receivers and related technology is not open
近年來我國無線電技術水平已經有了很大發展和進步,但對于頻率覆蓋范圍寬( 20 - 3000mhz ) 、掃描速度快( 1ghz / s以上)並具備快速全頻段實時頻譜顯示和記錄的無線電監測接收設備,目前我國尚不能生產,國內現在已經進口的寬頻段監測接收機一般也只能進行低速掃描,無法滿足實際的需要。The absolute calibration of hydrophones using the planar scanning technique in the frequency range 0, 5 mhz to 15 mhz
