英文摘要： The low-altitude airspace management reform of our country is now in the key period, therefore the demand for low-altitude surveillance equipments is very urgent. Single frequency network-based passive radar (SPR) is a new type of surveillance equipment, which has the following characteristics such as good low-altitude coverage performance, easy installation and deployment, low cost and good prospects for networking. SPR has important practical significance for improving the infrastructure construction with lower airspace opening, and so on promoting the development of general aviation in our country. Array calibration is the key technical problem that must be solved in the research and development of SPR, and has important scientific significance and considerable application prospect. From the specific working system and application environment of SPR, this project, with making full use of the signal resource, prior knowledge and previous research, aims to develop new array calibration methods for SPR and improve a matching total solution including: cognition and reconstruction of external radiation source signal; single frequency network channel estimation based on array antenna; array calibration parameter estimation adapted to complex multipath channel; prior knowledge mining, sorting and utilization; experi
