摘要:
Provided is a receiving device that is used for a spread spectrum radar apparatus, receives a spectrum-spread signal, and obtains a precise radar spectrum, and includes: a despreading unit that (i) generates first and second despread signals that are generated by despreading a reception signal using a pseudo-noise code, the second despread signal passing through a transmission line carrying a current having a current value identical to a current value of a current carried by a transmission line through which the first despread signal passes, and (ii) includes a first transistor pair including first and second transistors having an identical characteristic, the first transistor outputting the first despread signal, and the second transistor outputting the second despread signal; and a quadrature demodulating unit that generates an in-phase signal and a quadrature signal by quadrature-demodulating the first despread signal and the second despread signal, respectively.
