英文摘要： High sensitivity adaptive digital multi-beamforming navigation anti-jamming techniques based on space, frequency, code, and polarization domain will be studied under the Radio Navigation Satellite System (RNSS). By exploiting the advantages of high gain and strong interference resistance ability of multi-beamforming anti-jamming processing, we will focus on digital multi-beamforming anti-jamming methods and algorithms, parameters estimation of jamming signal and anti-jamming processing, joint processing methods and algorithms of space-time-frequency-polarization domain, and beam tracking and filtering of anti-jamming multi-beam. Some new concepts, theory, methods, and algorithms are hopeful to be proposed under the support of this project. Key scientific problems to be solved are involved in new adaptive anti-jamming methods with joint space-time-frequency-polarization processing, fast adaptation of the anti-jamming algorithms, and multiple targets optimization of performance, complexity, and robustness. We will try to achieve some innovative algorithms and conclusions of adaptive constraint multi-beam control, anti-jamming processing with multi-beam pointing to navigation signal direction of arrival, anti-jamming processing and algorithm with autonomic multi-beam tracking, joint anti-jamming processing of space
