SPREAD SPECTRUM RADAR APPARATUS, METHOD FOR DETERMINING VIRTUAL IMAGE, AND METHOD FOR SUPPRESSING VIRTUAL IMAGE |
摘要 |
The spread spectrum radar apparatus in the present invention (i) includes: a transmission code generator (110); a reception code generator (121) generating a reception code obtained by delaying a transmission code; a spread modulator (112) spread-modulating a signal generated by a local oscillator (111) using the transmission code; a transmission antenna (113) transmitting the spread-modulated signal; a reception antenna (120) receiving a signal; a spread demodulator (122) demodulating the signal using the reception code to provide a correlation signal; a mixer (123) mixing the correlation signal and the signal generated by the local oscillator (111) to generate a radar signal; a virtual image determining unit (130) determining a virtual image; and a radar signal calculation device (160) calculating the radar signal using a virtual image determination signal, and (ii) adds a calculation and an offset signal for suppressing a peak intensity of the virtual image when the virtual image occurs.
