Abstract

The frequency-modulated continuous wave (FMCW) synthetic aperture radar (SAR) has the properties of compact size, lightweight, low cost and low power dissipation, which provides great potential in the application of small platforms such as unmanned aerial vehicle (UAV). The imaging characteristics of rotary target for FMCW SAR are analysed based on the construction of echo signal model. Further, a passive suppressing jamming method for FMCW SAR based on micromotion modulation is proposed. This method makes use of rotary corner reflector to form jamming strips in range and azimuth, and then the target screened is protected effectively. The choice of parameters of rotary corner reflectors is discussed in detail. Finally, some simulations are given to validate the theoretical derivation and the effectiveness of method.
