Definitions

  • the radar device receives an antenna unit that radiates a radar wave into space and a reflected wave from a target of the radar wave via the antenna unit. It is provided with a high-frequency circuit that performs a high-frequency circuit and a baseband circuit that converts a received signal output from the high-frequency circuit into a digital value baseband signal. A plurality of receiving channels are configured in the antenna unit, the high frequency circuit, and the baseband circuit.
  • the radar device According to the radar device according to the present disclosure, there is an effect that the received SNR of the entire device can be improved while the high frequency circuit is not provided with the LNA.
  • the number of receiving channels is 4, but the number is not limited to this.
  • the number of receiving channels is plurality, the effect of the first embodiment can be enjoyed.
  • the number of transmission channels is set to 2, but the number is not limited to this.
  • the number of transmission channels may be 1 or 3 or more.
  • BBA20 The operation of BBA20 will be described in more detail.
  • the NB PCAs 11 voltage-amplify the same received signal output from the MIX 4.
  • the adder 12 adds each output signal of the PCA 11.
  • the input impedance of the BBA 20 is set sufficiently higher than the output impedance of the corresponding MIX 4.
  • the BBA 20 operates as a voltage amplifier.
  • an example of input impedance is 5 k ⁇ .
  • MIX4 an example of output impedance is 50 ⁇ .
  • S OUT is the output voltage of the received beat signal, that is, the output voltage of BBA 20 under each condition.
  • N OUT is an output noise in which the output noise generated inside the BBA 20 and the output noise of the MIX 4 amplified by the BBA 20 are combined by the root mean square under each condition.
  • ⁇ SNR which is the degree of improvement of the received SNR, is a dB notation of the difference value from each of the conditions (2) to (4) with the condition (1) as a reference. According to FIG.
  • the configuration shown in the above embodiment is an example, and can be combined with another known technique, and a part of the configuration is omitted or changed without departing from the gist. It is also possible.
