How do you find the cross section of a radar?

How do you find the cross section of a radar?

Radar cross section is the ratio of backscatter power to the power density received by the target….Factors on which Radar Cross Section depends

  1. Frequency of the radar signal.
  2. Distance between the target and the radar.
  3. Material of the target.
  4. The aspect and the orientation of the target to the radar source.

What are the dimensions of a tractor trailer?

The standard dimensions of semi-trailers are: Length: 48 – 53 feet (576 – 636 inches) Width: 8.5 feet (102 inches) Height: 13.5 feet (162 inches)

What is the length of a tractor and trailer?

A semi truck is about 70 feet long, combining the tractor and trailer. The length can vary considerably based on: Type of tractor: Sleeper cabs, which have a bed inside for drivers who haul farther away from home, are typically about 20 feet long, though each manufacturer and spec can alter that.

What is the equation for target cross section of SLL?

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.

What is the maximum width of a tractor trailer?

102.36 inches
Commercial motor vehicles, semi-trailers or tractor-hauled trailers also have a maximum width of 102.36 inches, while height is between 13 and 14 feet. Note that the federal government hasn’t set any limit on what a state can allow in terms of the height of semi-trailers.

What is the max length of a tractor trailer?

fhwa.dot.gov, search “length limits.” A semitrailer operated in a truck tractor and semitrailer combination is limited to 59 feet. 59 feet max. A truck and pole trailer combination may not exceed 65 feet in overall length.

What is high PRF?

A high PRF can be used to determine Doppler frequency and therefore relative velocity for all targets. It can also be used when a moving object of interest is obscured by a stationary mass, such as the ground or a mountain, in the radar return.
