基于OFDM随机步进频的雷达通信一体化信号模型
A Signal Model for Integration of Radar and Communication Based on Random Stepped-frequency OFDM Radar Pulses
摘要
Abstract
To solve the problem of signal separation in the system of integration of radar and communication, a signal model based on random stepped-frequency Orthogonal Frequency Division Multiplexing( OFDM) ra-dar pulses is proposed. By the frequency agility, the communication data is modulated on the radar pulses and then transmitted through random stepped-frequency pulses. Thus, the target range image can be ac-quired from the correlation of the echo signal and the reference signal, while the communication data is de-modulated by means of frequency detection through bandpass filter group without signal separation. Finally, simulation results show that the designed signal realizes decimeter range resolution imaging and high-rate da-ta transmitting in Mbit per second, which can satisfy the requirements of transmitting the mass data.关键词
