摘要：Radar is an electronic device that uses radio waves to determine the range,angle,or velocity of objects.Real-time signal and information processor is an important module for real-time positioning,imaging,detection and recognition of targets.With the development of ultra-wideband technology,synthetic aperture technology,signal and information processing technology,the radar coverage,detection accuracy and resolution have been greatly improved,especially in terms of one-dimensional(1D)high-resolution radar detection,tracking,recognition,and two-dimensional(2D)synthetic aperture radar imaging technology.Meanwhile,for the application of radar detection and remote sensing with high resolution and wide swath,the amount of data has been greatly increased.Therefore,the radar is required to have low-latency and real-time processing capability under the constraints of size,weight and power consumption.This paper systematically introduces the new technology of high resolution radar and real-time signal and information processing.The key problems and solutions are discussed,including the detection and tracking of 1D high-resolution radar,the accurate signal modeling and wide-swath imaging for geosynchronous orbit synthetic aperture radar,and real-time signal and information processing architecture and efficient algorithms.Finally,the latest research progress and representative results are presented,and the development trends are prospected.
