Abstract: To investigate the performance change and influence mechanism of quantum interference radar (QIR) system under the influence of charged sand particles, the relationship between charged sand particles and quantum link attenuation of QIR is established firstly based on the charge distribution and extinction coefficient of sand particles in an electric field. And then, the influences of different parameters of charged spherical and ellipsoidal sand particles on the resolution and phase sensitivity of the QIR are simulated under different photon emission numbers. The simulation results show that the QIR quantum link attenuation tends to increase with the increase of the charge-to-mass ratio of charged spherical sand particles, the equivalent radius of charged ellipsoidal sand particles, and the particle mass concentration. And under the given wavelength and the parameter influence of the charged sand particles, increasing the number of emitted photons will improve the QIR resolution and decreases the QIR sensitivity. It can be seen that the influence of the extinction effect of charged sand particles on the QIR performance cannot be ignored, and the simulation results can provide theoretical support for the further development and application of QIR technology in detecting targets in dusty weather.
