The versatility of Pushbroom Sensor Designs is outlined. Multiple line arrays of detectors are used in the focal plane to provide signal enhancement and track association data format for signal conditioning. Strong targets may be sensed without moving parts. Weak targets are sensed against earth background with a minimum of motion for alignment with a variable image motion direction. Very wide fields of view are covered by multiple telescopes and focal planes to illustrate a conceptual approach for meeting exceptionally wide swath coverage requirements. The options provided by using multiple line arrays of detectors in the pushbroom mode give unique capability to the sensor design.
