Abstract
Orthogonal Time Frequency Space (OTFS) is an innovative multicarrier modulation method known for its high resilience in challenging Doppler-affected environments, and the integration of communication and radar based on OTFS is expected to be the main development direction of communication and radar integration in unmanned high mobility combat scenarios in the future. In this paper, for the problem that the communication data in the integration of communication and radar based on OTFS would adversely affect the radar ambiguity function, the preprocessing of communication data by using coding sequences with excellent correlation was proposed to improve the effectiveness of the combined signal ambiguity function; furthermore, a Threshold-based Iterative Partial Transfer Sequence method was proposed to reduce the Peak-to-Side Lobes Ratio of the preprocessed integrated signal. The simulation results show that the optimized design scheme of the integrated signal proposed in this paper can improve the distance-dimensional ambiguity function of the integrated signal, and at the same time, the ability of the additive Gaussian White Noise is also significantly enhanced, which can reduce the impact of precoding on Peak-to-Average Power Ratio of the integrated signal, realize highly reliable communication transmission in the case of interference, and achieve excellent radar detection performance.
