The radio frequency susceptibility test method in reverberation chamber defined in RTCA DO160G required the time of the field strength remain above -3dB of the maximum value around the max field should be longer than the EUT response time. In general, with the same forward power injected in a chamber with two tuners, the greater the difference between two stirrers rotating speed, the greater the field strength will be received, but the effective time will be shorter. In this paper, we set 7 different rotating speed and measure the time in lGHz-2GHz band, there is an overall tendency for the effective time to decrease with increasing frequency for the same stirrer settings, and when two stirrers are set with different speed, the effective time is more affected by the stirrer with faster stirrer speed.

In this paper, the deviation contributions influenced by actual vector network analyzer (VNA) hardware features are determined. The raw and final measured values are regarded as multivariate functions of the error terms based on the widespread short-open-load-thru (SOLT) 12-term error model, with the linear terms of Taylor’s series near the ideal values of the error terms taken as reasonable estimations of the error. The calculated and ideal values of the error terms obtained in calibration steps are hence substituted to derive the deviation contributions of those terms to the raw and final measurement result. Two different VNAs (Keysight 5227A and Ceyear 3671E) are utilized to measure the network under test with known parameters serving the same calibration steps. In the research, reflection tracking error has the greatest influence on the raw measured values, but only the load mismatch error is a deviation contributor to the final measured values. The correctness and effectiveness of the method are verified by comparing the measurement results.

With the use of fly-by-wire flight control systems, and the replacement of key equipment in the semi-open area of the aircraft with sensitive electronic equipment, the design of electromagnetic protection in this area is particularly important. Regular long slit designs should be avoided in semi-open areas, thus creating some very strong resonance points in the area and exciting a harsh electromagnetic environment. A good structural design can effectively mitigate the enhanced effect of HIRF field strength in the semi-open area. This paper presents a simulation analysis for a typical Semi-Open structure and gives an optimization solution which has a good technical effect.

In order to reduce noise interference and improve the localization accuracy, the individual gunshots localization technology under the condition of low SNR is studied. In this study, muzzle blast wave endpoint detection technology based on sound intensity threshold, and sound source localization technology based on Stabilized Fast Transversal Recursive Least Square (SFTRLS) algorithm and microphone array model are used. Experimental result shows that even under the condition of low SNR, the muzzle blast wave endpoint detection technology and the sound source localization technology can still achieve a high accuracy on a small microphone array.

In recent years, surface electromyography (sEMG)- based neural decoding has shown prospective applications in rehabilitation medicine and smart prosthetics, and sEMG signals have been increasingly used to operate wearable devices. In order to develop an exoskeleton controller that can assist the human body to walk up stairs, we investigated the relationship between joint angle and surface EMG (including the effect of different algorithms on the predicted results) when the human body walks up stairs. Five subjects with normal joints participated in the experiment. In this paper, a new model-CNN-LSTM (Convolutional Neural Network- Long Short-Term Memory) is proposed to predict the angle of the knee joint. To reduce the crosstalk between different sensors, the ICA (Independent Component Analysis) algorithm was used as a data preprocessing method. The method is shown to be efficient by comparing the prediction results of the algorithms. This is the first step towards myoelectric control of an assisted exoskeleton robot using discrete decoding. The results of this study will lead to the development of future neurologically controlled mechanical exoskeletons that will allow people who need assistance to perform more activities.

In order to solve the electromagnetic compatibility (EMC) problem of the high precision measurement system in a research center, the EMC characteristics of the measurement system and the surrounding electronic equipment are analyzed. The mechanism that the sensors in the measurement system are susceptible to electromagnetic interference is analyzed in depth, and the common measures to protect them from electromagnetic interference are introduced. It is determined that the main electromagnetic disturbance source around the measuring system is the servo drive system. The composition of servo drive system and the characteristics of electromagnetic disturbance are introduced and analyzed. The electromagnetic immunity characteristics of the measurement system are tested, including conducted immunity and radiated immunity. The electromagnetic emission characteristics of the servo drive system are tested, including conducted emission and radiation emission. The EMC immunity level curve of the measurement system is obtained by analyzing the test data.
