In this paper, a multi-navigation source fusion method based on information geometry (Kullback-Leibler Divergence Minimization, KLM) is proposed, which maps the information accuracy probability function of each navigation source to the Riemann space, and establishes the navigation source information probability set manifold. The optimal fusion of the information geometric manifold of the navigation source under the Riemann information geometry architecture. This method uses the K-L divergence to replace the geodesic distance, which greatly reduces the amount of calculation and effectively improves the overall positioning accuracy. The simulation results show that after the information of each navigation source is fused by the KLM method, the positioning error obtained after fusion is significantly reduced.

{"title":"A Signal demodulation algorithm for high-speed inter-satellite link based on double closed-loop structure","authors":"Peihan Yu, Hongwei Zhao, Chengkai Tang, Bernie Wang","doi":"10.1109/ICSPCC55723.2022.9984556","DOIUrl":"https://doi.org/10.1109/ICSPCC55723.2022.9984556","url":null,"abstract":"The inter-satellite link plays an important role in the process of realizing global connection, which is expected to be fast, efficient and seamless. It also builds an integrated communication network between space and earth. Since the inter-satellites are generally far away from each other, and they move relatively at high speed in their own respective orbits, which will bring large path loss and Doppler shift. When using high-frequency communication, the Doppler shift is more obvious, which has a serious impact on the data recovery at the receiver and cannot meet the reliability requirements for communication. Aiming at the above problems, this paper proposes a new demodulation algorithm based on double closed-loop structure. The Walker inter-satellite link is adopted firstly, then we designed the transmission frame structure. Finally we propose a complete modulation and demodulation scheme. In the demodulation scheme, We use the Delayed Auto Correlation (DAC) method for the super-frame header to improve the capture performance when the signal to noise ratio (SNR) is low. Then, for the spread spectrum signal, an improved timing error detection method is proposed. It reduces the processing bandwidth, and improves the accuracy of timing error detection under the condition of low SNR. What’s more, it is easy to implement. The simulation results show that when the SNR is greater than 13dB, the proposed algorithm can quickly complete the synchronization, and the bit error rate (BER) is less than 10-6, which meets the requirements of the received signal level of the inter-satellite link.","PeriodicalId":346917,"journal":{"name":"2022 IEEE International Conference on Signal Processing, Communications and Computing (ICSPCC)","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134027899","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}

In the airport, the interference and Countermeasure of the competition venue against UAVs has become the core link of security in large-scale events and important places. The existing interference sources are mainly single point interference. Due to the shielding of buildings, it is impossible to fully cover the venue. Therefore, distributed interference optimization is the best option to combat large-scale UAVs in the future. On the basis of summarizing the jamming benefit evaluation system, this paper introduces the probability of jamming source discovery as the jamming cost, and establishes the satellite navigation distributed jamming optimization model. Tabu search artificial bee colony algorithm (TSABC) is proposed to solve the problems of slow interference speed and low success rate of traditional distributed interference optimization algorithm. The algorithm proposed in this paper is compared with ABC algorithm and PSO algorithm in interference countermeasure scenario. The simulation results show that the TSABC algorithm proposed in this paper effectively improves the interference efficiency and can quickly and accurately interfere with a large number of UAVs.","PeriodicalId":346917,"journal":{"name":"2022 IEEE International Conference on Signal Processing, Communications and Computing (ICSPCC)","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131164620","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}

Effectively compensating for the uncertainties and disturbances mentioned above to ensure the good attitude of the UAV, brings a significant challenge to the design of control system. The active disturbance rejection control (ADRC) has the characteristic of good estimation and compensation ability for uncertainty and is independent of the controlled object.

To improve the azimuth resolution, a large coherent accumulation angle or a sufficient observation time duration is required, which is difficult to achieve in practical applications. To overcome the sparse aperture problem of a photonics-based ISAR, azimuth super-resolution imaging is demonstrated in this paper, in which the sparse representation method is applied to implement sparse azimuth data extrapolation or fusion. In the experiment, the photonics-based radar has a bandwidth of 8 GHz, and ISAR echoes from a full observation aperture are selected to imitate the short-aperture detection and sparse aperture detection, respectively. Performance of the sparse-representation-based azimuth super resolution imaging method is investigated.
