Range Relationships
The bistatic range equation is similar in form to the monostatic range equation and is derived in a similar process. The principal-and obvious-difference in the equations is that RTRR replaces R2 M, where RT is the bistatic transmitter-to-target range, RR is the bistatic receiver-to-target range, and RM is the monostatic transmitter-and receiver-to-target range. This simple difference causes significant differences in monostatic and bistatic radar operation. One major difference is that bistatic thermal noise-limited detection contours are defined by ovals of Cassini, rather than by circles for the simplest monostatic case. These ovals are particularly useful in defining regions where the bistatic radar can operate.
