The invention relates to a roadside dual beam microwave radar traffic flow detection device and a roadside dual beam microwave radar traffic flow detection method. The roadside dual beam microwave radar traffic flow detection device comprises a first antenna, a second antenna, a first microwave transceiving module, a second microwave transceiving module, a waveform generating module, an intermediate frequency filtering module, an AD acquisition module, a DSP co-processor, a DSP main processor and a communication interface. The first antenna and the second antenna are placed on the roadside and vertical to the lane direction for transmitting and receiving microwaves, a digital signal processor DSP acquires echoes, and the DSP main processor and the DSP co-processor conduct statistical calculation on traffic flow, occupation ratio and average vehicle speed. According to the roadside dual beam microwave radar traffic flow detection device and the roadside dual beam microwave radar traffic flow detection method, the microstrip antennas capable of transmitting two independent wave beams are adopted, information of ten bidirectional lanes can be detected at most, and the system can adapt to various kinds of ground clutters, harsh weather conditions and vast dust interference in an industrial field.
