Abstract:
The RF Generator is the core component of Coherent Doppler weather rad ar, and the components are the highpriced due to high level technics. It prov ides all ne cessary radar working signals of benchmark, and has altogether 5output signals , na mely the 9.6 MHz master clock signals, COHO signal, RF DRIVE signal, STALO signa l , and RF TEST SIGNAL. Because different regions use different working frequenc y of ra dar’s transmitters, then the RF Generator can not be universal, and a compon ent backup is unrealistic in stations. On the other hand, radar manufacturers d id not provide the RF Generator drawings, and it brought difficulties to determine fau lt reasons. For the more than 10 CINRAD/SA radar RF Generator failures, the pape r divides three types of failures and analyzes the specific repairing methods. Finally, b y analyzing the frequency internal structure, we put forward the method or techn ique of resolving failures which the radar operator and maintenance professional should master so as to enhance the station’s security capacity.
