The basic concept of the new data reduction and compaction approach presented in this paper is to process on-board the satellites, the sensor raw data output essentially on a comparison/correlation basis, with stored targets' signatures. In this manner only pertinent target information, extracted from the vast raw sensor data, will be downlinked, therby substantially reducing total bits transmitted.
