"Three stereo radar techniques for producing stereo images from which topographic data and maps may be obtained are described and their performance in the presence of system errors is determined. The techniques are: an improved single flight technique which uses a combination of two antenna beam characteristics which permits terrain illumination from nearly the same aircraft position, a previously proposed single flight technique which uses two horizontal linear arrays generating vertical fan beams at different azimuth angles, and an existing two flight technique which uses a horizontal array generating a side-looking fan beam.
Error analyses are performed to determine the feasibility of the two single flight techniques. Comparisons are made of the error performance of all three techniques.
The analyses show that: (1) both single flight techniques are feasible and could be employed using present day state-of-the-art sensing devices, (2) the most significant error sources for the single flight techniques are the aircraft angular errors, conical beam cone angle error, and imaging errors, while the two flight technique is in general most sensitive to aircraft position and ranging errors, (3) the improved single flight technique has the best performance with errors and the previously proposed single flight technique performs better than the two flight technique when errors are present"--Abstract, page ii.
