This invention discloses an optimized method for deception jamming of frequency-hopping radar based on a four-dimensional antenna array. This method addresses the problem of existing four-dimensional antenna arrays failing to jam against broadband radars with rapidly changing frequencies due to beam squint effects. It constructs a broadband array pattern model with the entire radar frequency hopping point set as variables and establishes a hierarchical optimization cost function. This function prioritizes suppressing the echo from the true target direction to below a safe threshold across the entire frequency band, and then maximizes the minimum gain in the direction of the false target. A differential evolution algorithm is used to globally optimize the RF switching timing parameters of each array element, obtaining a set of frequency-independent robust optimal timing sequences. Loading these timing sequences into the controller enables the four-dimensional antenna array to stably achieve deception jamming effects that conceal the true target and enhance the false target across the entire frequency hopping bandwidth of the radar without real-time adjustments. This effectively overcomes the aperture crossing effect and ensures the robustness of jamming when the enemy radar frequency changes.
