摘要
En 中文
To utilize a unified waveform to realize radar and covert communication functions simultaneously, we propose a novel high speed covert dual function radar communication waveform using phase-reduced shift keying and code-domain index modulation (HCDFRC-PRSK-CDIM). First, the spherical codes are selected for code-domain index modulation to improve the communication rate. In addition, the binary phase shift keying scheme with a reduced phase are introduced to embed the information in linear frequency modulation (LFM) signals with covertness. Simulation results show that the designed waveform has good covertness and bit error rate (BER) performance without affecting radar detection performance.
