Abstract

Abstract : Frequency diverse array (FDA) can provide a range‐angle‐dependent beam by controlling the frequency increment between adjacent elements. However, in conventional FDA, the frequency increment is fixed, resulting in a significant restrain of jamming performance in various environments. With the above finding, the authors propose an optimal frequency increment selection method by maximising the output signal‐to‐interference‐plus‐noise ratio in each coherent processing interval for multiple‐input–multiple‐output‐FDA radar. In addition, the discrimination method for the target and the jamming is studied. Simulation results demonstrate that jamming can be effectively discriminated and suppressed with the radar configuration, and better performance is achieved with an optimal frequency increment.
