Design of a compact, modular, multi-frequency band, multi-mode, multi-channel synthetic aperture radar

Compact, flexible synthetic aperture radar (SAR) systems have proven their utility on a number of manned and unmanned aircraft. These systems can be even more useful when configured with multiple frequency bands, multiple channels, and/or multi-mode operation. This paper presents the design of a compact, modular, multi-frequency, multi-mode, multi-channel SAR. The modular design increases flexibility, allowing for an arbitrary number of transmit and receive channels, facilitating multiple-input, multiple output (MIMO) operation.
