Abstract

The conventional single carrier frequency antenna pattern has a narrow main lobe level, but its side lobe level cannot be greatly reduced, which is not conducive to the improvement of the anti-interference effect. Based on this, this paper applies the sinusoidal weighted multi-carrier frequency scheme to the Frequency Diverse Array (FDA) and compares the performance of the antenna patterns of several FDA structures using the sinusoidal weighted multi-carrier scheme. It can be seen from the simulation results that compared with the single carrier frequency and other multi-carrier frequency schemes, the performance of the FDA regime radar such as SL-FDA is significantly improved after applying the sinusoidal weighted multi-carrier frequency scheme. The main lobe width in the range dimension is narrowed, and the side lobe level is also effectively suppressed. The sinusoidal weighted multi-carrier scheme is significantly better than other multi-carrier schemes.
