Spatio-Temporal Cascaded Algorithm for DOA Estimation of Coherent Signal Sources in Low-Altitude Targets over Sea Surfaces

In this article, we explore the application of the spatio-temporal cascaded algorithm for DOA estimation of coherent signal sources from low-altitude targets over sea surfaces. First, let us understand the concept of the spatio-temporal cascaded algorithm. This algorithm is an advanced signal processing technique used to model and process signals in both spatial and temporal domains. It integrates signals from multiple sensors to obtain more accurate data, thereby enhancing the resolution and localization precision of target signals. In DOA estimation for low-altitude targets over sea surfaces, the algorithm determines target direction by analyzing arrival time and phase differences of signals across different sensors. By implementing this approach, we can achieve more precise DOA estimates compared to traditional methods, improving the understanding and identification of low-altitude maritime targets. Thus, the spatio-temporal cascaded algorithm holds broad application prospects in fields such as marine monitoring and military reconnaissance.
