Embodiment Construction

[0016] The design method of each module of the incoherent scattering radar simulation system will be described in detail below in conjunction with the accompanying drawings.

[0017] Such as figure 1 As shown, the incoherent scatter radar simulation system adopts the concept of modular design, and divides the system into signal simulation module 101, incoherent scatter spectrum simulation module 102, ionospheric parameter analysis module 103, The radar power simulation module 104 and the antenna array simulation module 105 have basically the same functions as the radar system extensions. In order to provide the system with the necessary evaluation capabilities, the system also adds two supplementary modules, the radar hardware performance evaluation module 106 and the radar detection performance evaluation and signal flow graph module 107 . The transmission and sharing of data and information can be realized between each module, and it can also run independently according to ...

Abstract

The invention provides an ionized layer incoherent scattering radar simulation system, which is characterized in that a modular design idea is adopted, the system is divided into a signal simulation module, an incoherent scattering spectrum simulation module, an ionized layer parameter analysis module, a radar power simulation module and an antenna array simulation module according to a radar actual system structure and functions of each extension set, module functions are basically the same as completing functions of each system extension set, transmission and sharing of data and information among the modules can be realized, and dynamic demonstration is carried out by using an MATLAB graphical user interface function. The ionized layer incoherent scattering radar simulation system well solves a problem that the incoherent scattering radar is small in number of research platform and difficult in test, and can help the technicists to improve abilities of analyzing and solving problems and an ability of carrying out radar equipment technical research.

Description

technical field [0001] The invention relates to a radar simulation system, which is suitable for the simulation verification of an incoherent scattering radar system. Background technique [0002] Incoherent scatter radar uses the weak scattering signals of electrons and plasma thermal fluctuations in the upper atmosphere to remotely measure the physical parameters of the upper atmosphere. Since the scatter signal caused by this thermal fluctuation is incoherent, it is called incoherent scatter radar. Incoherent scatter radar is the only device capable of measuring plasma density, velocity, and temperature over the entire range of ionospheric heights (80-1000 km), and deriving electric and wind fields from plasma parameters. It has the outstanding advantages of measuring high-altitude atmospheric physical parameters, high precision, large measurement height range, and high distance resolution. It is currently the most advanced means for ground detection of space atmospheric...
