Abstract

An improved FMCW auto-collision radar system is introduced. The system includes perfect binary sequences pairs theory, the method using auto-correlation functions to get target signal and measure distance, this enables itself to get constant development with theoretical progress. The new system only changes the program of signal generator a little, moreover it can be realized by DSP, which can reduce the false alert notably so as to be applied increasingly widely. Key words: stepped-frequency modulation; multi-target detection; perfect binary sequences pairs
