In order to fully understand the situation of electromagnetic interference generated by onboard portable electronic equipment on each electronic equipment on an airplane, a common method is to test the airplane on site by a tester.
However, the conventional method has the following problems that the test period is long, the measurement efficiency is low and the test cost is increased due to the fact that the operation and the steps which need to be executed by a tester in a field test are complicated.
In order to solve the above problem, the following embodiments will describe and explain a simulation test method for antenna induced strong electromagnetic pulse coupling effect provided by the embodiments of the present application in detail.
Referring to fig. 1, a schematic flow chart of a simulation test method for antenna induced strong electromagnetic pulse coupling effect according to an embodiment of the present invention is shown. In this embodiment, the simulation test method for the antenna induced strong electromagnetic pulse coupling effect may be applied to a terminal or a server with simulation software.
As an example, the simulation test method for antenna induced strong electromagnetic pulse coupling effect may include:
s11, an antenna equipment model with an output port and an environment platform with an input port are constructed in a simulation mode, the antenna equipment model is arranged in the environment platform, and the environment platform is a carrier platform with electronic equipment in a simulation mode.
Before the antenna equipment model and the environment platform are set up in a simulation mode, a user can determine the type of the electromagnetic pulse required by the simulation test, define a waveform expression corresponding to the type of the electromagnetic pulse, generate the corresponding electromagnetic pulse by defining the waveform expression, and perform the test by using the electromagnetic pulse.
In this embodiment, the electromagnetic pulse related to the method may include a high-altitude nuclear explosion electromagnetic pulse (HEMP) and a high-power microwave (HPM), and then a waveform expression of the high-altitude nuclear explosion electromagnetic pulse and a waveform expression of the high-power microwave are taken as preset waveform expressions.
The waveform expression of the high-altitude nuclear explosion electromagnetic pulse is as follows:
E(t)＝κ×E0(e-αt-e-βt)

The output port of the antenna device model may be a feed port, which may in particular be a discrete port. The environment platform can be a carrier platform simulating and provided with various electronic devices including antenna device models, such as a free space carrier platform, an airplane carrier platform, a ship carrier platform, a vehicle carrier platform and the like.

And adjusting the electromagnetic pulse signal wave by adjusting the parameters so as to generate a plane wave required by the test.
S13, obtaining power parameters output by the output port of the antenna equipment model through induction through a preset time domain solver, judging whether the antenna equipment is influenced by electromagnetic pulses according to the power parameters, and generating a test result.
In this embodiment, the simulation test terminal is further provided with a time domain solver, and the time domain solver may be configured to obtain a power parameter output by the antenna device model and determine whether the antenna device model receives the influence of the electromagnetic pulse according to the power parameter.
