In view of the characteristic of all-domain openness of tactical network, a Weighted-type Fractional Fourier Transform-based encryption modulation scheme of physical layer constellation is proposed based on the aliasing characteristic of WFRFT signal constellation diagram. On this basis, the influence of weighted parameters on system safety capacity and reliability is considered, and WFRFT weighted parameters are optimized. The simulation results show that when SNR is 15dB, the BER of the system meets the requirements of secure communication, and the low interception performance of the system will be well realized.
