The system for evaluating the influence of the wind power plant on the radar detection performance comprises a multipath effect and shielding angle calculation module, a Doppler calculation module, a field intensity distribution calculation module and a directional diagram calculation module. A simulation scene modeling module and a simulation result display module are arranged in each of the multipath effect and shielding angle calculation module, the Doppler calculation module, the field intensity distribution calculation module and the directional diagram calculation module, and are used for performing simulation scene modeling and simulation result display on calculation results of the corresponding calculation modules; and electromagnetic solving modules are arranged in the field intensity distribution calculation module and the directional diagram calculation module. According to the method, the influence of the wind power plant on the radar in different states can be calculated, the radar can be better guaranteed, the radar service guarantee level is improved, meanwhile, effective guidance is provided for scientific site selection of the wind power plant, and wind power resources are efficiently utilized.

Description

technical field [0001] The invention relates to the technical field of electromagnetic compatibility between a wind farm and a radar system, in particular to a system for evaluating the influence of a wind farm on radar detection performance and its application. Background technique [0002] Due to the increasing tension of traditional non-renewable energy and the increasingly prominent environmental protection issues, green and clean renewable energy has received great attention. Wind energy, due to its advantages of being clean, non-polluting, and renewable, has been flourishing, prompting the rapid development of wind farms. However, due to the massive construction of wind farms and their huge structures and complex electromagnetic scattering characteristics, the impact of wind farms on warning radar, communication and navigation has become increasingly prominent, and it is a huge challenge to radar protection. Therefore, before the construction of a wind farm, it is nec...

Problems solved by technology

According to the Doppler effect, the rapid rotation of the blade will cause the Doppler frequency shift of the reflected signal, which will cause a certain error in the radar's identification of the target

[0008] With the rapid development of the wind power industry, the scale of wind farms is also increasing. However, when the relevant departments build wind farms, they take wind resources as the main consideration and ignore the electromagnetic characteristics of wind farms. a series of disturbances
