WebNov 11, 2024 · Abstract: Bistatic backscatter communication (BackCom) allows passive tags to transmit over extended ranges, but at the cost of having carrier emitters either transmitting at high powers or being deployed very close to tags. Bistatic radar is a radar system comprising a transmitter and receiver that are separated by a distance comparable to the expected target distance. Conversely, a conventional radar in which the transmitter and receiver are co-located is called a monostatic radar. A system containing multiple spatially diverse … See more Pseudo-monostatic radars Some radar systems may have separate transmit and receive antennas, but if the angle subtended between transmitter, target and receiver (the bistatic angle) is close to zero, then … See more The principal advantages of bistatic and multistatic radar include: • Lower procurement and maintenance costs (if using a third-party transmitter). • Operation without a frequency clearance (if using a third-party transmitter). See more • Bistatic sonar • CLidar • GNSS reflectometry • Radar cross section See more Angle The bistatic angle is the angle subtended between the transmitter, target and receiver in a … See more Bistatic imaging is a radar imaging technique using bistatic radar (two radar instruments, with one emitting and one receiving).
