Some embodiments are directed to a radar imaging system that includes a radar transmitter configured to transmit radar at a target; an aperture including an array of physically independent airborne carriers, each of the carriers configured to receive radar echoes from the target; and a base station, which may be located at ground level, in communication with each of the airborne carriers to receive the radar echoes and determine an image of the target from the received radar echoes.

Radar imaging system

A method and apparatus for processing of a signal in which a variation in phase between a transmitted and reflected pulse is modeled, as is the amplitude of the pulse. The modeled phase and amplitude are used to smooth the data by reducing phase noise present on the signal thereby enhancing the signal to noise ratio.
