Which factors determine the range resolution of a radar?
Andrew Vasquez Which factors determine the range resolution of a radar?
Range resolution is the ability of a radar system to distinguish between two or more targets on the same bearing but at different ranges. The degree of range resolution depends on the width of the transmitted pulse, the types and sizes of targets, and the efficiency of the receiver and indicator.
Which factor determines the range resolution of a radar Mcq?
Pulse width is the primary factor in range resolution. A well-designed radar system can distinguish targets separated by one-half the pulse-width time (τ).
How is radar range of resolution calculated?
Range resolution as a distance can be calculated as follows: Rres = c * τ /2 Where, τ is the transmitted pulse width and c is the velocity of light in the free space. Narrower beamwidth is very useful to distinguish two adjacent targets.
What is the range accuracy requirement for radar system?
Radar Range and Bearing Accuracy: The RADAR Range accuracy should be within 30 m or 1% of the range scale in use, whichever is greater. And for bearing the accuracy should be within 1%.
On which factor the maximum range of radar depends?
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. The pulse repetition rate (PRR) determines the maximum measurable range of the radar.
What is range resolution and bearing resolution?
Bearing, or azimuth, resolution is the ability of a radar system to separate objects at the same range but at different bearings. The degree of bearing resolution depends on radar beam width and target range. Range is a factor in bearing resolution because the radar beam spreads out as range increases.
What is maximum range of radar?
The maximum range of the Radar for given specifications is 128km.
What is the maximum range of a radar?
128km
The maximum range of the Radar for given specifications is 128km. The minimum range is defined by the pulse width. The time for the radar pulse to travel from the radar to a target 1 mile. Radar range is increased by the peak power.
How is PRF calculated on radar?
PRT is also equal to the sum, PRT = PW+RT. PRF = pulse repetition frequency. 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.
What is radar bearing resolution?
Bearing resolution is the ability of the radar to display as separate pips the echoes received from two targets which are at the same range and close together. It is proportional to the antenna length and reciprocally proportional to the wavelength.
