Abstract

Signal based motion compensation (SBMC) is an enabling technology for low cost SAR applications as well as an enhancement for more robust SAR applications. SBMC involves down range and cross range compensation for platform motion with motion compensation signals derived entirely from radar signal based measurements. It is an alternative to motion measurement sensor (MMS)-based motion compensation and a next step growth from autofocus. A very robust SBMC algorithm has been developed and demonstrated on simulated data and real radar data provided by actual radars. The algorithm is tuned to a particular radar and adapted to any level of aircraft navigation system. This SBMC approach will enable a low cost SAR capability to be provided for budget minded applications. Alternately, it can also be applied to high performance SAR systems for improved capability. It will extend current MMS motion compensation and autofocus performance and provide a backup capability to compensate for navigation system performance degradation, such as from component failure or GPS jamming.

基于信号的运动补偿

基于信号的运动补偿(SBMC)是一种低成本SAR应用的使能技术，也是增强更强大SAR应用的技术。SBMC涉及平台运动的下距和跨距补偿，其运动补偿信号完全来自基于雷达信号的测量。它是基于运动测量传感器(MMS)的运动补偿的替代方案，也是自动对焦的下一个发展方向。提出了一种鲁棒性很强的SBMC算法，并在实际雷达提供的模拟数据和真实雷达数据上进行了验证。该算法适用于特定的雷达，并适用于任何级别的飞机导航系统。这种SBMC方法将为预算紧张的应用提供低成本的SAR功能。另外，它也可以应用于高性能SAR系统，以提高能力。它将扩展当前的MMS运动补偿和自动对焦性能，并提供备份功能，以补偿导航系统性能下降，如组件故障或GPS干扰。
