For the bistatic radar configuration—transmitter and receiver separated (not co-located) -- the bistatic radar cross-section (BRCS) is a function of both the transmitter-target orientation and the receiver-target orientation.
For basic considerations of the strength of a signal returned by a given target, the radar equation models the target as a single point in space with a given radar cross-section (RCS). The RCS is difficult to estimate except for the most basic cases, like a perpendicular surface or a sphere.
When it is exactly zero the radar is a monostatic radar, when it is close to zero the radar is pseudo-monostatic, and when it is close to 180 degrees the radar is a forward scatter radar. Elsewhere, the radar is simply described as a bistatic radar. The bistatic angle is an important factor in determining the radar cross section of the target.
When a target is within this range, the radar receives an adequate target skin return to track it. The burn through range is a function of the target RCS (Radar cross-section), jamming ERP (Effective radiated power), the radars ERP and required J/S (for the jamming to be effective).
The original AN/AWG-10 can detect an aerial target with 5 square meters radar cross section more than 100 kilometers away. AN/AWG-10A is a development of the original AN/AWG-10, with great improvement in reliability and maintainability by replacing the original transmitter in AN/AWG-10 with a solid state unit whose only tube was a klystron ...
The radar mile is the time it takes for a radar pulse to travel one nautical mile, reflect off a target, and return to the radar antenna. Since a nautical mile is defined as 1,852 m, then dividing this distance by the speed of light (299,792,458 m/s), and then multiplying the result by 2 yields a result of 12.36 μs in duration.
The United States' National Radar Cross-section Facility (commonly abbreviated as RATSCAT) is located at Holloman AFB, New Mexico. The Lockheed Have Blue and Lockheed F-117 Nighthawk have been tested at this site.
The radar frequency is also chosen in order to optimize the radar cross-section (RCS) of the envisioned target, which is frequency-dependent. Examples of propagation windows are the 3 GHz (S), 10 GHz (X), 24 GHz (K), 35 GHz (Ka), 77 GHz (W), 94 GHz (W) propagation windows.
