Problems solved by technology

It can be seen from the figure that the azimuth pattern of the traveling wave array waveguide antenna is composed of a single waveguide, and there are only sum beams and no difference beams, and the target cannot be tracked stably for a long time, only the search mode can be used, so it cannot be further improved. Azimuth and elevation angle measurement accuracy

Abstract

The invention discloses an angle measuring method, an angle measuring device and an angle measuring system. The angle measuring method comprises the following steps of: performing hopping-frequency intwo different working frequency points to obtain the point information of the two different working frequency points, wherein the point information comprises an amplitude value corresponding to the azimuth angle; performing a sum operation of the amplitude values on the point information of the two different operating frequency points to obtain amplitude sum value and performing a difference operation of the amplitude values to obtain an amplitude difference value; dividing the amplitude sum value by the amplitude difference to obtain an amplitude ratio; obtaining a target amount according tothe amplitude ratio and an azimuth corresponding to the amplitude ratio; calculating the angle of the target based on the miss distance. The angle measuring method, the angle measuring device and theangle measuring system of the embodiment can stably track the target for a long time because of not only the beam and the difference beam, thereby improving the accuracy of the azimuth and the elevation angle.

Description

technical field [0001] The invention belongs to the technical field of radar detection, and in particular relates to an angle measuring method, an angle measuring device and an angle measuring system. Background technique [0002] In recent years, with the improvement of radar detection performance requirements, while vigorously developing radio frequency components and signal processing technologies, higher requirements have been put forward for antennas. Rectangular waveguide slot array antennas have been widely used in radar systems due to their small size, light weight, high aperture efficiency, and low sidelobe, especially in Ku-band (12GHz-18GHz) and Ka-band (27GHz-40GHz). ) high frequency radar. [0003] For example, if figure 1 As shown, although the traveling wave array waveguide antenna has the advantages of wide bandwidth and good matching design, it has the disadvantages of deviation between the maximum radiation direction and the normal direction of the antenn...
