This invention discloses a multi-domain joint error correction system for a dual-frequency swarm array, belonging to the field of radar signal processing technology. It obtains correction signals from multiple correction sources through time diversity, with each source transmitting correction signals to the swarm array with a position error exceeding half a wavelength via two carrier frequencies. A simplified SMSSWF method is used to estimate the actual steering vectors of the two carrier frequencies. Based on these steering vectors, the equivalent frequency method is used to calculate the position error, obtaining estimated values ​​for the array element position error parameters. After updating the array element position information using these estimated values, the received signals from the two carrier frequencies are used to estimate the position error, phase error, and communication delay error, respectively, completing the joint error correction for the swarm array with a position error exceeding half a wavelength. The dual-frequency position error estimation based on the equivalent frequency method fully utilizes the large error estimation range of the dual-frequency method while retaining the high accuracy of traditional methods, successfully correcting errors even when the position error exceeds half a wavelength.
