| The research on automotive anti-collision radar of Intelligent Transport System has spreaded in world wide range. Anti-collision radar has very important use to increase traffic security and decrease accident loss,the research on which has huge realistic meaning and wide application foreground. Focused on the realization in engineering practice, this paper introduces automotive anti-collision radar's function requirement,system design. Based on dicussing distance-measurement mode,this paper discusses carrier frequency and modulation scheme and modulation signal wave and system basic structure of automotive anti-collision radar. This paper introduces the design of data-sampling system of anti-collision radar. This paper analyses the realization process of software and hardware design of data-sampling system, cpld design and system performance. |
