How do you find the range of a radar?

How do you find the range of a radar?

Standard Form of Radar Range Equation Therefore, we can say that the range of the target is said to be maximum range when the received echo signal is having the power equal to that of minimum detectable signal. We will get the following equation, by substituting R=RMax and Pr=Smin in Equation 6.

How is RCS calculated?

A target’s RCS (σ) is most easily visualized as the product of three factors: σ = Projected cross section x Reflectivity x Directivity . RCS(σ) is used in Section 4-4 for an equation representing power reradiated from the target. For a sphere, the RCS, F = Br2, where r is the radius of the sphere.

What is G in radar range equation?

A radar equation relates the range of a radar to the characteristics of the transmitter, receiver, antenna, target, and distance. Consider a monostatic radar. Let Pt be the transmitted power, G the antenna gain, R the distance of the target.

What is meant by radar range?

The maximum distance at which a radar set can detect a specified object at least 50% of the time.

What are the parts of RCS in radar?

The RCS of this figure can be divided into the Rayleigh region, the Mie or the resonance region, and the optical region. In the Rayleigh region, where the size of the sphere is small compared with the wavelength, the RCS varies with λ4.

What is antenna gain formula?

Therefore, in terms of the true gain (relative to an isotropic radiator) G, this figure for the gain is given by: For instance, the above antenna with a gain G=5 would have a gain with respect to a dipole of 5/1.64 = 3.05, or in decibels one would call this 10 log(3.05) = 4.84 dBd.

How do you calculate PRF?

1. Where.
2. PRF = Pulse Repetition Frequency (Hz)
3. PRT = Pulse Repetition Time.
4. c= 3 x 108 m/s (Speed of Light)

What does RCS mean in radar?

Definition of Radar Cross Section (RCS or σ) Radar Cross Section is the area intercepting that amount of power which, if radiated isotropically, produces the same received power in the radar.

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.

What is a radar equation?

A radar equation relates the range of a radar to the characteristics of the transmitter, receiver, antenna, target, and distance.

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 much power does it take to detect radar signals?

The maximum radar detection range is; The variables in the above equation are constant and radar dependent except target RCS. Transmit power will be on the order of 1 mW (0 dBm) and antenna gain around 100 (20 dB) for an effective radiated power (ERP) of 100 mW (20 dBm). Minimum detectable signals are on the order of picowatts;
