Embodiment Construction
[0034] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.
[0035] In addition to causing blocking effects, strong electromagnetic radiation can also cause fluctuations in ground potential, instantaneous drop in power supply voltage, and failures such as restarts, crashes, dysfunction, and display errors in the tested equipment. Although these electromagnetic radiation effects appear in different locations, their internal causes are the same - ground poten...

The invention belongs to the technical field of electromagnetic environment effect test evaluation, and provides a multi-source strong field electromagnetic radiation effect prediction method and device. The multi-source strong field electromagnetic radiation effect prediction method comprises the steps that a sine amplitude modulated wave electromagnetic radiation effect test and a single-frequency continuous wave electromagnetic radiation effect test are separately performed on a plurality of out-of-band frequency points of tested frequency equipment; a multi-frequency electromagnetic pulsetrain radiation sensitivity type and a corresponding prediction model of the tested frequency equipment are determined; and multi-source strong field electromagnetic radiation effect prediction is performed on the tested frequency equipment. According to the multi-source strong field electromagnetic radiation effect prediction method and device, strong field electromagnetic radiation signals are divided into carrier-wave-containing electromagnetic pulse trains and transient high-intensity electromagnetic pulse radiation without a carrier wave according to the difference in waveform characteristics and duration of the strong field electromagnetic radiation signals, and radiation effect modeling is performed on the electromagnetic pulse trains and transient high-intensity electromagnetic pulses separately to achieve evaluation of failures such as restart, crash, dysfunction and display errors caused by the high-intensity electromagnetic radiation.
Description
technical field [0001] The invention belongs to the technical field of electromagnetic environment effect test evaluation, and in particular relates to a multi-source strong field electromagnetic radiation effect prediction method and equipment. Background technique [0002] The in-band receiving sensitivity of the frequency equipment is high, and it has strong selectivity to the signal frequency. Once the frequency of the interference signal is far away from its working frequency, the critical interference field strength will increase rapidly. When the out-of-band electromagnetic radiation reaches a certain intensity, because the antenna receives a wide frequency range, even if the receiver has frequency selection capability, some energy of the interference signal will still enter the receiver after being limited and filtered, resulting in a decrease in the gain of the useful signal. cause blocking effect. [0003] In addition, strong electromagnetic radiation will also ca...
