First Claim
Patent Images
1. A bistatic system comprising:
- a bistatic transmitter for transmitting electromagnetic energy, said transmitter having a first velocity-to-range ratio relative to a target; and
a bistatic receiver for receiving said electromagnetic energy reflected from said target, said receiver having a second velocity-to-range ratio relative to said target, wherein the velocity-to-range ratio of the receiver is approximately equal to the velocity-to-range ratio of the transmitter.

Abstract
A bistatic radar system and method. In the illustrative embodiment, a receiver is positioned in a horizontal plane. A transmitter is then positioned in Middle Earth Orbit at a position that is nearly vertical to the plane of the receiver. This configuration provides significant flexibility for the radar system. As such, the radar system may engage in flight patterns, in which the transmitter and receiver have velocity vectors in opposite directions (GMTI mode), the same direction (SAR mode) and variations in between (mixed mode). Lastly, a broad beam is generated from the transmitter and illuminates an area enabling several receivers to simultaneously observe the illuminated area.
