Embodiment Construction
[0028] The invention provides a fast search method based on the whole airspace early warning one-dimensional rotating phased array radar. In the present invention, the azimuth dimension search and the pitch dimension search are carried out synchronously, wherein the pitch dimension adopts phase scanning, and the azimuth dimension adopts mechanical scanning. The schematic diagram of the beam scanning is as follows figure 2 with image 3 shown. At the same time, combined with the actual radar system, under the actual situation that the "2 out of 2" rule is adopted and the radar beam pointing is not synchronized with the wave position processed by the signal processor, the search process is divided into the target detection process and the target confirmation process. Only when a target is detected in the process does it need to enter the target confirmation process, and its airspace search flow chart is as follows Figure 4 shown.
