| titleOfInvention | Doppler frequency velocimeter |
| abstract | The utility model discloses a Doppler frequency velocimeter which comprises a power supply panel and also comprises a first microwave transceiver, a second microwave transceiver, a first preamplifier circuit board, a second preamplifier circuit board and a signal processing board, wherein the first microwave transceiver is connected with the first preamplifier circuit board, the second microwave transceiver is connected with the second preamplifier circuit board, both the first preamplifier circuit board and the second preamplifier circuit board are connected with the signal processing board, and the signal processing board is connected with the power supply panel; an absolute value of the difference between an included angle formed between a transmitting wave of the first microwave transceiver and the ground and an included angle formed between a transmitting wave of the second microwave transceiver and the ground is a nonzero constant value. The Doppler frequency velocimeter has the advantages of high accuracy in train speed measurement, good result reliability and good anti-jamming capability in the complex environment. |
