Embodiment Construction

[0017] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] Simulink is a visual simulation tool in MATLAB. It is a block diagram design environment based on MATLAB. It is a software package for dynamic system modeling, simulation and analysis. It is widely used in linear systems, nonlinear systems, digital control and In modeling and simulation of digital signal processing. Simulink can model with continuous sample time, discrete sample time, or a mixture of the two. It also supports multirate systems, that is, different parts of the system have different sample rates. In order to create a dynamic system model, Simulink provides a graphical user in...

Abstract

The invention discloses a simulink-based non-coherent scattering radar echo simulation method and a system. The method comprises the following steps of simulating and emitting a radar pulse signal by a radar pulse emitter in simulink, amplifying the power of the radar pulse signal by a transmitter, increasing the gain of the radar pulse signal by a transmitting antenna, scattering the radar pulse signal by a target simulation ionized layer to form an echo signal, filtering the signal by a receiver analog front end, processing the signal by a receiver digital processing module, outputting a related signal of the echo signal by an output module, and importing the simulated echo signal into the MATLAB for further treatment. According to the invention, the process of sending the radar pulse signal and scattering the outputted radar pulse signal by the ionized layer to form the echo signal can be simulated. Therefore, the scientific research personnel can be helped to get rid of limitation of radar equipment conditions. No expensive radar equipment is required to acquire related radar echo data. Therefore, radar echoes scattered by the ionized layer can be simulated conveniently and flexibly.

Description

technical field [0001] The invention relates to the technical field of radar simulation, in particular to a Simulink-based incoherent scattering radar echo simulation method and system. Background technique [0002] Incoherent scattering radar (ISR) is the most powerful ground-based equipment for detecting the ionosphere. It detects the weak scattering signals generated by the thermal fluctuations of electrons and ions in the ionosphere, which is different from fixed targets such as aircraft, missiles and ships detected by conventional radars. , incoherent scattering radar has many advantages such as strong detection function, many parameters, high precision, good resolution, and large height coverage. However, the radar equipment is bulky and the operating cost is very expensive. Therefore, the main incoherent scattering radars in the world do not start up for a long time, only about two to three months a year. Due to the high cost of using incoherent scatter radar, it has...
