| 摘要 |
The radar apparatus of the present invention can obtain distance to a target and speed with higher accuracy even when multiple targets are running within a detecting field of a radar. The radar apparatus can transmit a radio wave by alternately switching a section having a frequency slope and a section having no frequency slope with the radar for simultaneously transmitting a couple of frequencies having a frequency difference. Measurement of distance to the target and relative speed is conducted in the above two sections, results of measurement are compared with each other in the adjacent sections, and the result of measurement is determined correct only when there is no inconsistency in these measurement results.
