Abstract
Integration of radar and communication on the electronic war platform is an effective method to reduce volume and enhance spectrum usage and efficiency. A transmitted pattern based on OFDM-LFM MIMO radar is designed to realize the integration of radar and communication by changing initial frequency. The communication receiver interpretation of the bit is based on the initial frequency of the signal. In radar receiver, the same range resolution as tradition OFDM-LFM MIMO radar can be get with get the time domain synthetic bandwidth methods. The proposed method changes the initial frequency without changing the omnidirectional pattern because the orthogonal transmitted signals are nonoverlapping in the spectrum. Simulation examples are provided for performance evaluation and to demonstrate the effectiveness of the proposed information embedding technique.
