The Radar Range calculator computes the radar range based on the source power, antenna efficiency and area, the wavelength, radar cross-section and the power received.
INSTRUCTIONS: Choose units and enter the following:
- (PS) This is the source power
- (Ka) This is the antenna efficiency
- (A) This is the antenna area
- (λ) This is the signal wavelength
- (σ) This is the radar cross section
- (PE) This is the power received
Radar Range (R): The range is returned in meters. However this can be automatically converted to compatible units via the pull-menu.
The Math / Science
The formula for the range radar is:
`R = root(4)((P_S * G^2 * λ^2 * σ)/((4π)^3·P_E))`
where:
- R is radar range
- G is the gain:
- `G = (4 *pi * A * K_a)/lambda^2`
- PS is the source power
- Ka is the antenna efficiency
- A is antenna area
- λ is the signal wavelength
- σ is the radar cross section
- PE is the power received
This Radar Range Equation computes the range that can be derived from the relationship between the following inputs.
- The transmitted power emitted from the antenna that is propagated out and back from the radar target
- The antenna gain
- The radar cross section of the target
- The power received
