## What is the maximum range of radar?

Therefore, the maximum range of Radar for given specifications is 158KM.

### What are the factors determining the maximum possible range of a radar?

The maximum range of a radar system depends in large part on the average power of its transmitter and the physical size of its antenna. (In technical terms, this is called the power-aperture product.) There are practical limits to each. As noted before, some radar systems have an average power of roughly one megawatt.

#### What is the range for radar?

Range is the distance from the radar site to the target measured along the line of sight. The factor of two in the equation comes from the observation that the radar pulse must travel to the target and back before detection, or twice the range.

How much increase in transmitted power is needed to make the range of the radar double?

In order to double the range, the transmitted power would have to be increased by 16-fold! In order to double the range, the transmitted power would have to be increased by 16-fold!

What is minimum range of radar?

The minimum range capability of a radar is determined primarily by the pulse length. It is equal to half the pulse length of the radar (164 yards per microsecond of pulse length).

All advanced ground-based radars don’t stop working on cloudy days. Surveillance radars detect enemy or invading aircraft even on cloudy days as electromagnetic waves from radars travel in straight line and even penetrate clouds. However, dense clouds could weaken the signals.

Raindrops absorb and scatter radar signals, so less energy reaches the target and even less returns to radar as an echo. Hence, precipitation (rain, snow, hail etc.) Second, there is a returned signal from the rain which ‘clutters’ the radar return and can mask targets.

#### What happens to the range of radar when the transmission power is doubled?

Since Rmax ∝ (Pt)1/4, to double Rmax, Pt must be increased by a factor of 16. Since Rmax ∝ D1/2, If the antenna aperture is doubled i.e. if the diameter is doubled, the radar range will be increased by √2.

What are the factors affecting minimum range?

What factors affect Minimum Range of RADAR?

• The minimum range capability of a radar is determined primarily by the pulse length.
• Sea return or echoes received from waves may clutter the indicator within and beyond the minimum range established by the pulse length and recovery time.

Radar waves travel through the atmosphere at roughly 300,000 km per second (the speed of light). The range to a target is determined by measuring the time that a radar signal takes to travel out to the target and back.

## How to calculate the maximum range of a radar?

Calculate the maximum range of Radar for the following specifications. We know the following formula for operating wavelength, λ in terms of operating frequency, f. Substitute, C = 3 × 10 8 m / s e c and f = 10 G H Z in above equation.
