摘要：
The work considers the formation of a spatiotemporal signal at the output of a linear antenna array and the characteristics of this signal in the frequency domain. The concept of signal broadband in the spatiotemporal sense is discussed and its effect on signal detection against a background of active interference is considered. Based on the study of the spatiotemporal spectral characteristics of the signal and active interference in the radar system, an approach to signal processing based on the spatiotemporal spectral analysis is proposed.
