Abstract

Abstract:

Integrated radar and communication system can reduce the volume of electronic equipment and improve the spectral efficiency, which is one of the important research directions in multifunctional integration of electronic system. On the basis of random pulse repetition interval (PRI) agility radar, a novel signal design method for integrated radar and communication based on PRI agility is proposed. The communication information is embedded in the transmitting signal by changing the transmitting signal of PRI. At the radar receiver, compressed sensing theory is used to realize coherent integration and velocity super-resolution estimation of target. At the communication receiver, the communication information is demodulated by detecting PRI of pulse. The simulation results verify that the signal design method for integrated radar and communication can realize stable transmission of communication information on the premise of not affecting radar detection performance.

Key words: integration of radar and communication, signal sharing, pulse repetition interval (PRI) agility, compressed sensing, velocity super-resolution
