Abstract :
Aiming at the application of the OFDM wideband imaging radar, a new chaotic phase-coded OFDM (COFDM) signal is advanced in this paper, which has many advantages, such as flexible code, agile length and so on. And then, a method based on chaotic decoding and sub-carrier bandwidth synthesis is proposed to realize pulse compression of this signal. Finally, experiments validate its pleasant performance of high range resolution and anti-jamming, comparing with P3 and P4 code.
