It is rather difficult due to the complex motion resulting in energy spread in time and frequency domain. Also, high detection performance and computational efficiency are difficult to balance in case of more integration pulses. In this paper, we propose a fast and refined processing method of radar maneuvering target based on hierarchical integration detection, utilizing the advantages of moving target detection (MTD), fractional Fourier transform (FRFT) and fractional ambiguity function (FRAF). The method adopts two-stage threshold processing. The first stage is the coarse detection processing screening out the range units having possible moving targets. The second stage is called the refined processing, which uses FRFT or FRAF for coherent integration dealing with high-order motions, i.e., accelerated or jerk motion. And the second stage is carried out only within the rangebins after the first stage. Therefore, the amount of calculation can be greatly reduced while ensuring high detection performance. Finally, real radar data are used for verification of the proposed method, which shows better performance than the traditional MTD method with higher integration gain.","PeriodicalId":382686,"journal":{"name":"2019 IEEE 2nd International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121116445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We train convolution neural network (CNN) on amplitude and phase (AP) samples, which are two-dimension matrices consisting of amplitudes and phases extracted from complex-valued baseband signals. The performance of our proposed method is confirmed in both light-of-sight (LOS) and non-light-of-sight (NLOS) channel.

Compared to other general three-level inverter configurations, the control strategy of this dual two-level inverter structure is more flexible. But with a single dc power supply in the OEW-induction motor drive system, many negative effects will be brought due to the presence of common mode voltage, such as causing circulating current in the winding and reducing system reliability. Owing to elimination the negative effect of the common mode voltage, one way is to synthesize the reference voltage with the switching combinations which do not produce common model voltage. However, the maximum modulation will greatly be reduced with these switching combinations being used. In order to maintain the maximum modulation while the common mode voltage is suppressed, a novel SVPWM scheme for this structure has been proposed. It is illustrated that the average of common mode voltage of the system is suppressed in each sampling-time interval by adjusting the placement of voltage space vectors and reasonable voltage selection. In addition the switching frequency of this novel control strategy for dual two-level inverter system is equal to the traditional SVPWM control strategy, and it has a significant improvement of the maximum linear modulation index. The proposed modulation control strategy has been verified by the simulation on a MATLAB platform.","PeriodicalId":382686,"journal":{"name":"2019 IEEE 2nd International Conference on Electronic Information and Communication Technology (ICEICT)","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130090703","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

That means the gait cycle detection is the first step. We proposed a posed-based method to detect the gait cycle, which could obtain prominent and accurate gait cycle. Particularly, giving a video sequence we take advantage of the latest pose estimation network to get the human skeleton, as well as the position of the key points. Then the distance of two ankles is calculated. By the variation of distance with the sequence, we could get the accurate gait cycle.
