on angular resolution imposed by wavelength and antenna aperture,<br />

but it should be said that the possibilities of storage inherent in the<br />

mosaic method might eventually offset to some degree the other apparent<br />

disadvantage of the system—its low sensitivityy. As usual in c-w radar,<br />

knowledge of target range would not be afforded by such a system<br />

without further elaboration.<br />

If range is taken into account, the rate at which the radar collects<br />

information can be computed in a very direct way. Under ideal circumstances<br />
