This talk will discuss two nontraditional approaches to forming images of a scene from data collected by a single moving radar sensor.
The first is a method for forming images from data measured by a moving antenna emitting a single-frequency continuous wave. This imaging method relies on the fact that different points in the scene correspond to a different Doppler history. This scheme could be useful in situations where the available transmit spectrum is severely limited.
The second part develops an approach for using standard synthetic-aperture radar (SAR) data to produce images that show the localized frequency dependence of scattering. This could be referred to as hyperspectral SAR, or perhaps backscatter color imaging. Such images could perhaps be useful for identifying materials, local geometrical shapes, or resonant structures.
