## What is radiradar range equation?

**Radar**range equation is useful to know the range of the target theoretically. In this chapter, we will discuss the standard form of**Radar**range equation and then will discuss about the two modified forms of**Radar**range equation.

## How to calculate the maximum range of radar for given specifications?

- We can use the following modified form of Radar range equation in order to calculate the maximum range of Radar for given specifications. R M a x = [ P t σ A e 2 4 π λ 2 S m i n] 1 / 4. Substitute, the given parameters in the above equation. R M a x = [ ( 400 × 10 3) ( 30) ( 5 2) 4 π ( 0.003) 2 ( 10) − 10] 1 / 4.

## How do you calculate the power density of a radar?

- Consider a monostatic radar. Let Pt be the transmitted power, G the antenna gain, R the distance of the target. Then, the power density at the target is given by: (10.4)P d = PtG 4πR2. Assume the target receives the incident power with an area σ, called the radar cross section (RCS), and radiates isotropically.
