Abstract

Abstract:

The conventional Frequency diverse array (FDA) employs the fixed frequency increment，which restricts its applications in various environments. With the above findings，we propose an optimal frequency increment selection method based on oblique projection filtering for mainlobe interference suppression. We can obtain the optimal frequency increment by maximizing the output SINR of the oblique projection filter in each coherent processing interval (CPI). Inspired by the cognitive radar，the optimal frequency increment will be used in the next CPI. Simulation results demonstrate that jamming can be effectively suppressed with the radar configuration，and that better performance is achieved with an optimal frequency increment.

Key words: frequency diversity, oblique projection, mainlobe, frequency increment, filtering
