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.
How do you double radar range?
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 should be considered while calculating the range of radar?
Calculate the maximum range of Radar for the following specifications.
- Operating frequency, f=10GHZ.
- Peak power transmitted by the Radar, Pt=400KW.
- Effective aperture of the receiving Antenna, Ae=5m2.
- Radar cross section of the target, σ=30m2.
- Power of minimum detectable signal, Smin=10−10W.
How do I increase my radar range?
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 maximum range of radar?
The maximum range of the Radar for given specifications is 128km.
Why radar range Cannot be predicted accurately using simple radar range?
It is difficult to predict the range of the target from the standard form of the Radar range equation. Because, the parameters like Radar cross section of the target, σ and minimum detectable signal, Smin are statistical in nature.
How the radar range can be increased?
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.
Why the radar range Cannot be predicted accurately using simple radar range equation?
How is PRF calculated on radar?
10.2 Parameters of a Pulsed Radar PRF is the rate that pulses repeat per second and is equal to the inverse of PRI. The fraction of the total time that the transmitter is on is called the duty cycle dc. It can be determined by measuring the time required by the pulse to travel to the target and return.
What does the range equation on a radar mean?
The radar range equation represents the physical dependences of the transmit power, which is the wave propagation up to the receiving of the echo signals.
Do you need to double the range of a radar?
To (roughly) double the range of radar, you not only need to double the range of the transmitted signal, but double the range of the reflected signal, in order to produce the same received signal level.
How does the peak power of a radar affect its range?
The peak power of a radar is its useful power. Range capabilities of the radar increase with peak power. Doubling the peak power increases the range capabilities by about 25 percent.
How big is a minimum detectable radar signal?
Minimum detectable signals are on the order of picowatts; RCS for an automobile might be on the order of 100 square meters. The accuracy of the radar range equation is only as good as the input data.
