What is the unit of radar?

PRF has units of time-1 and is commonly expressed in Hz (1 Hz = 1/s) or as pulses per second (pps). PRF is the number of pulses transmitted per second and is equal to the inverse of PRT. RF = radio frequency. RF has units of time-1 or Hz and is commonly expressed in GHz or MHz.

How far can radar travel?

Detection range can be as low as 100 feet or less to over a mile. A radar may track a distant large vehicle instead of a closer small vehicle without any indication to the operator which vehicle the radar is tracking.

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.

What are the factors affecting the minimum range?

What factors affect Minimum Range of RADAR?

• PULSE LENGTH. The minimum range capability of a radar is determined primarily by the pulse length.
• SEA RETURN.
• SIDE-LOBE ECHOES.
• VERTICAL BEAM WIDTH.

What is the unit of radar resolution?

At any range, with similar azimuth and elevation angles and as viewed by a radar with an unmodulated pulse, the range resolution is approximately equal in distance to half of the pulse duration times the speed of light (approximately 300 meters per microsecond).

What is the minimum range capability of a radar that is determined primarily by the pulse length?

The pulse width (H) determines the minimum range at which targets can be detected. This minimum range is approximately ½ the length of the wave burst.

What is meant by minimum detectable signal in radar?

A minimum detectable signal is a signal at the input of a system whose power allows it to be detected over the background electronic noise of the detector system. It can alternately be defined as a signal that produces a signal-to-noise ratio of a given value m at the output.

Can radar be used on land?

Today, military services still represent the main area of usage for radar technology, as military applications on land, in the air, and at sea rely on radar. Among these applications are threat detection, missile guidance, air and marine navigation, and more.

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.

How can I increase my radar range?

Range capabilities of the radar increase with peak power. Doubling the peak power increases the range capabilities by about 25 percent. The longer the pulse length, the greater is the range capability of the radar because of the greater amount of energy transmitted.
