The invention relates to the technical field of power amplifiers, and particularly discloses a pulse power
amplifier and a pulse radiator, the actual heating state of a device is accurately reflected by acquiring the temperature distribution of each stage of power
amplifier device in real time and judging the
delay of a sensor, and a hot spot determination and temperature prediction identification module is used for determining the temperature of the device. A real hot spot area can be identified, the over-temperature risk can be predicted based on the temperature trend, advanced protection is realized, and the damage probability of a power tube or a synthetic link is reduced; the influence of
delay monitoring and environmental disturbance is analyzed based on temperature distribution parameters, and a monitoring hot spot position is verified and determined, so that the accuracy of
temperature control and hot spot identification is improved; the pulse radiator associates temperature abnormity with
radiation parameter fluctuation, identifies leading influence factors, ensures accurate and stable
microwave output, integrally realizes real-time monitoring and prediction protection of temperature abnormity and
radiation output, triggers protection actions in advance, and improves
operation safety and reliability.
