A pulse radar determines target by round trip time of a pulsed microwave signal. The frequency used by radar transmitter is 10GHz with transmitted power 2KW (Pulse power). The Antenna size of radar transmitted this signal is based on \(\lambda\ (\text{Wavelength})=\frac{C\ (\text{speed of light})}{f\ (\text{Frequency})}\) with a Gain (Gt) of 28dB is used to detect the target (aeroplane) having its cross section area as 12m2. The receiver has its capability as -90dBm as minimum detectable signal (Pmin). There is an isolation between trans and receive chain as (80-100dB) determine Radar maximum range. Based on the paragraph answer following questions :
Operating frequency of this radar falls in which band ? specify it
X-Band
The question is asking about the specific frequency band in which a radar, operating at a frequency of 10 GHz, falls.
Radars can operate in different frequency bands, commonly known by names such as L-Band, C-Band, X-Band, and Ku-Band. Each of these bands falls within a specific frequency range:
- L-Band: 1 to 2 GHz
- C-Band: 4 to 8 GHz
- X-Band: 8 to 12 GHz
- Ku-Band: 12 to 18 GHz
The frequency provided in the comprehension is 10 GHz. This frequency falls within the X-Band range, which is from 8 GHz to 12 GHz.
Therefore, the correct answer is the X-Band. Here's a breakdown of why other options are incorrect:
- L-Band: This band encompasses frequencies from 1 to 2 GHz. 10 GHz is out of this range.
- C-Band: This band covers frequencies from 4 to 8 GHz, again excluding 10 GHz.
- Ku-Band: This band includes frequencies from 12 to 18 GHz. 10 GHz does not lie in this range.
Conclusion: The operating frequency of 10 GHz is within the X-Band range, therefore, the correct option is X-Band.
