Pulse Doppler weather radar receiver

The invention discloses a pulse Doppler weather radar receiver which comprises an antenna, a receiving module, a digital receiver and a main unit. Signals received by the antenna are sequentially transmitted through a surface acoustic wave filter, a radiofrequency filter and a frequency mixer and then are outputted to the digital receiver, the digital receiver is connected with the main unit, the main unit is connected with a test instrument and a processor, a memory and a temperature sensor are connected with the processor, and the processor is connected with a numerical-control attenuator. The pulse Doppler weather radar receiver has the advantages that the main unit is a PC (personal computer) or an industrial personal computer, large quantities of artificial participation procedures can be replaced, the pulse Doppler weather radar receiver is high in automation degree, and high-efficiency debugging can be implemented; the pulse Doppler weather radar receiver is provided with the single processor, the nume
