FMICW用于单基机载SAR的成像研究
Research on FMICW in Monostatic Airborne SAR Imaging
摘要
Abstract
Isolation between transmitter and receiver can't be solved when frequency modulated continuous wave(FMCW) SAR is applied in monostatic airborne platform.Aiming at this problem, frequency modulated interrupted continuous wave(FMICW) is proposed in monostatic airborne SAR imaging.Based on the characteristics of FMICW signal, the restraint condition of the parameters in FMICW SAR including gate pulse width, gate pulse repetition frequency, gate pulse number in a sweeping period, and sweeping frequency etc., are discussed in details.System construction of FMICW SAR is given and signal processing modules are analyzed.Finally, simulation is conducted for FMICW SAR based on range-Doppler(RD) algorithm to validate the proposed model.Results show that the airborne FMICW SAR can not only solve the isolation effectively, but also realize accurate imaging of targets.关键词
