Abstract:
According to the internal structure, working principles and maintenance requirements of the frontstage component of the Sband newgeneration weather radar high frequency amplification chain and important functional modules such as solidstate amplifier and RF pulse former, a set of diagnosis system which can support the test and maintenance of the solidstate amplifier and RF pulse former is designed. The design flow of the system is described in detail, mainly including the design of hardware, power, circuit interface, control logic and display circuit. It can provide a variety of voltage, control signal, timing logic signal for testing and maintenance of the solidstate amplifier and RF pulse former, thus meeting the circuit signal testing requirements of solidstate amplifier and RF pulse former faults, and judging fault points and components. The directoutput fault indication allows to conduct tests and fault location quickly, thus to ensure the safety of the maintenance personnel and to protect the radar equipment from secondary damages and assuring the timeliness of radar fault maintenance.
