Signal detectability in SS-BSAR with GNSS non-cooperative transmitter

The power budget analysis is considered for signal detection in bistatic synthetic aperture radar, with global navigation satellite systems acting as non-cooperative transmitters. The signal detection is analysed against thermal noise, in addition to interferences introduced by the transmitting satellites sharing the same frequency bands. Two basic configurations are considered: the radar receiver is on an aeroplane; and positioned stationary on the ground.
