First Claim
Patent Images
1. A synthetic aperture radar assembly locatable on a satellite for radar imaging of a planet surface in swaths, comprising:
- means for transmitting pulses of electromagnetic radiation towards the planet surface to be imaged in widths of swaths to be imaged,timing means, coupled to said transmitting means, for randomly varying the frequency of transmission of said pulses to increase the width of swath imageable;
means for receiving echoes of said pulses returned by said planet surface, andmeans for creating an image of a swath of said planet surface from said returned echoes.

Abstract
A synthetic aperture radar assembly (1) locatable on a satellite (2) for radar imaging of a planet surface (3) in swaths, including means (8) for transmitting pulses (4) of electromagnetic radiation towards the planet surface (3) to be imaged, means (8) for receiving echoes of said pulses (4) returned by said planet surface (3), means for creating an image of a swath (5) of said planet surface (3) from said returned echoes and means for randomly varying the frequency of transmission of said pulses (4) to increase the width (11) of swath (5) imagable.

3. A method of creating a radar image of a planet surface in swaths, comprising the steps of:
-
transmitting pulses of electromagnetic radiation from a satellite towards the planet surface to be imaged in widths of swaths to be imaged, randomly varying the frequency of transmission of said pulses to increase the width of swath imageable, receiving echoes of said pulses returned by said planet surface, and creating an image of a swath of said planet surface from the returned echoes. - View Dependent Claims (4, 8, 9, 10)
