This paper designs co-located MIMO-OCDM signals to reduce the transmission power of the signals, thereby reducing the maximum interception distance of the electronic reconnaissance receiver. After the power of the LFM signal is evenly distributed to each co-located MIMO-OCDM sub-chirp signal, the maximum interception distance of the electronic reconnaissance receiver decreased by 58.81 meters, and the working factor decreased by 36.67%. The designed co-located MIMO-OCDM signals have good low-interception performance and have certain engineering application value. |
