[0002] The statements in this section are provided only as background information in connection with this disclosure and may not constitute prior art.
[0003] As a core component of space infrastructure design, remote sensing satellites profoundly impact the progress of Earth science, resource management, and commercial activities. With a coverage radius of thousands of kilometers, remote sensing satellites can operate 24 / 7, monitoring key areas of global concern. In recent years, driven by technological advancements, capital investment, and market demand, the field of remote sensing satellites is undergoing a profound transformation. By deploying a large number of low-Earth orbit small satellites to form constellations, high-frequency revisits to any location globally are achieved, enabling dynamic monitoring and emergency response. Improved data processing capabilities have enabled automated decoding of massive amounts of data, significantly increasing the efficiency of converting raw data into final information products. To meet the minute-level response requirements in disaster emergencies and other scenarios, remote sensing satellite information can be directly transmitted to the requesting party via radio frequency links. Therefore, there is an urgent need in this field for design methods for novel receiving antennas capable of providing comprehensive and reliable reception of such information, thereby driving the evolution of remote sensing satellite information towards real-time and universal accessibility.
[0004] Driven by the aforementioned new technological demands, the design methods for receiving antennas in data receiving systems that receive remote sensing satellite signals have not yet been perfected. Therefore, this paper proposes a design method for core performance indicators of data receiving antennas for receiving remote sensing satellite data in typical application scenarios, focusing on the design of the receiving elevation angle, the number of receiving beams, and the receiving G / T value. Receiving antennas designed according to this method can meet the data receiver's requirements for receiving remote sensing satellite data, enabling efficient information customization services for the data receiving system through the received remote sensing satellite data.

[0026] The features and performance of the present invention will be further described in detail below with reference to embodiments.
[0027] Example 1 This embodiment proposes an optimized design method for remote sensing satellite data receiving antennas based on performance and application scenarios. Its core lies in taking application scenarios and system performance as fundamental principles, applying them throughout the entire design process for receiving elevation angle, receiving G / T value, and simultaneous multi-beam capability, thus achieving a transformation from passive adaptation to proactive optimization. The receiving elevation angle is transformed from a fixed technical parameter into one that is relevant to application scenarios and user-focused performance, enabling adaptive adaptation to scenarios and linking it to system performance. The three previously relatively independent core indicators—receiving elevation angle, receiving G / T value, and simultaneous multi-beam capability—are organically integrated into a smart, adaptive, and high-efficiency overall solution, upgrading remote sensing satellites into intelligent information hubs empowering various industries.

The remote sensing satellite dispersion radius analysis model is invoked, and the dispersion radius of the remote sensing satellite is determined based on the received elevation angle. The receiving multibeam analysis model is invoked, and based on the dispersion radius, the maximum number of satellites falling within the receiving beam range during the entire remote sensing satellite return cycle, under the constraint of the receiving elevation angle, is determined. This number serves as the simultaneous multibeam count index for the data receiving antenna; that is, determining the maximum possible number of remote sensing satellites within the receiving beam range under the constraint of the receiving elevation angle of the remote sensing satellite data receiving antenna.
