Abstract
The design of an orbital SAR mission is the result of a number of trade-offs. For example,
a higher resolution requires more transmitted power, or an increase in the strip-map
azimuth resolution results in a smaller possible swath. In the following sections the most
relevant parameters of a SAR system are discussed and the inter-relation between different
parameters is explored.
It is important to emphasize right away that the most critical trade-offs are not
technological but are, instead, fundamental in nature. For example, while the transmitted
power may be increased through technological improvement, the dimensions of an
antenna, given some basic specifications, are lower bounded by first principles.
It is also worth noting that the scope of this study is limited to currently operational SAR
configurations, as the goal of this project is to evaluate the feasibility of an operational
SAR mission on a compact platform, and not to propose novel SAR concepts. Where
necessary in our analysis we have chosen the option most compatible with the nature of a
small mission. For example, within the margin of possible orbital altitudes, the lower range is assumed since it reduces the required power.
