Abstract
The spread spectrum radar apparatus in the present invention (i) includes: a transmission code generator (); a reception code generator () generating a reception code obtained by delaying a transmission code; a spread modulator () spread-modulating a signal generated by a local oscillator () using the transmission code; a transmission antenna () transmitting the spread-modulated signal; a reception antenna () receiving a signal; a spread demodulator () demodulating the signal using the reception code to provide a correlation signal; a mixer () mixing the correlation signal and the signal generated by the local oscillator () to generate a radar signal; a virtual image determining unit () determining a virtual image; and a radar signal calculation device () 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.
