Low Cost UWB X-Band LFMCW-SAR

摘要：

　　For near range high resolution SAR(synthetic aperture radar)imaging,this paper presents an scheme for generating X-band LFMCW signal with 5.1GHz bandwidth based on YIG oscillator.The method is simple in structure and low in price,but introduces a certain degree of nonlinearity,resulting in range-resolution degradation.This paper first introduces the design of the radar transmitter.After that,with the existing HAF-based(high-order ambiguity function)nonlinearity correction method and ωk imaging algorithm,well focused range profiles and SAR images are obtained.Measurement results are used to validate the effectiveness of the algorithm.In the end,several SAR images are given to shown the performance of the radar system.
