合成孔径雷达（SAR）系统的性能取决于多种因素，其中许多因素以某种方式相互依赖。确定可实现的性能极限的问题通常很难“得到你的手臂”，然而这些极限是存在的，并且是由物理决定的，无论负责生成系统设计的工程师多么聪明。本报告确定并探讨了这些限制，以及它们如何取决于硬件系统参数和环境条件。最后，这将导致一个参数的特性，提供最佳性能的整个SAR系统。例如，存在取决于天气条件和范围的确定的最佳频带，并且固定的真实的天线孔径尺寸的最小雷达PRF与频率无关。虽然这里的信息并不是新的文献，它的收集到一个单一的报告希望提供一些价值，减少“寻找时间”。
The performance of a Synthetic Aperture Radar (SAR) system depends on a variety of factors, many which are interdependent in some manner. It is often difficult to 'get your arms around' the problem of ascertaining achievable performance limits, and yet those limits exist and are dictated by physics, no matter how bright the engineer tasked to generate a system design. This report identifies and explores those limits, and how they depend on hardware system parameters and environmental conditions. Ultimately, this leads to a characterization of parameters that offer optimum performance for the overall SAR system. For example, there are definite optimum frequency bands that depend on weather conditions and range, and minimum radar PRF for a fixed real antenna aperture dimension is independent of frequency. While the information herein is not new to the literature, its collection into a single report hopes to offer some value in reducing the 'seek time'.
