Abstract
A pulse transmission controller generates transmission timing signals for a high-frequency radar transmission signal in every transmission cycle. A transmission phase shifter gives a transmission signal generated by a modulator phase shifts each corresponding to a transmission cycle on the basis of the transmission timing signals generated at intervals that are equal to the transmission cycle. A reception phase shifter gives a reception signal that is output from an A/D converter reception phase shifts that are opposite in direction to the respective transmission phase shifts given by the transmission phase shifter on the basis of the transmission timing signals generated at intervals that are equal to the transmission cycle.
Claims14
A radar apparatus comprising:
- a pulse transmission controller that generates transmission timing signals for a high-frequency radar transmission signal in every transmission cycle;
- at least one code generator that generates at least one code sequence having a prescribed code length;
- a modulator that generates a baseband transmission signal by modulating the at least one code sequence on the basis of the transmission timing signals;
- a transmission phase shifter that gives the baseband transmission signal phase shifts each corresponding to at least one transmission cycle on the basis of the transmission timing signals;
- and
- an RF transmitter that converts a phase-shift-added transmission signal into the high-frequency radar transmission signal and transmitting the latter from a transmission antenna.
