| titleOfInvention | Code modulation radar ranging device and rear-end collision prevention device using the same |
| abstract | (57) [Summary] [Problem] To realize an inexpensive high-performance code modulation radar ranging apparatus having high distance resolution and not affected by mutual interference. PN An electromagnetic wave code-modulated or spectrum-spread at a frequency specified by the reference transmitter 2 is transmitted from the transmitter 3 toward the object to be measured, and the electromagnetic wave reflected by the object is transmitted to the receiver 4. To encourage. The reference code generator 8 generates the same code as that of the modulation code generator, code-modulates the same with a reference oscillator 9 that emits a frequency slightly different from that of the reference oscillator, and then modulates the received signal with a correlator 10. To find the correlation value with In the case of a reflected wave, the correlation value increases, and the processor 12 measures the distance based on the correlation value. By further providing an azimuth sensor 13 and using a different code according to the azimuth of the transmission direction of the transmission code, the code transmitted from the opposite device can be distinguished from the reflected wave because the azimuth is different. |
