Answer / Suraj Tiwari

The choice of frequency in FMCW (Frequency Modulated Continuous Wave) Radar instruments depends on the application, range resolution, and operating environment. The design basis for choosing the frequency is typically determined by factors such as:

1. Range Resolution: Lower frequencies provide better range resolution but may require larger antennas and more power to achieve acceptable performance. Higher frequencies offer smaller range resolution but can penetrate through obstacles more effectively.
2. Operating Environment: The environment where the radar will be used plays a significant role in determining the frequency choice. For example, operating in urban areas might require lower frequencies due to the presence of buildings and other structures that can disrupt higher-frequency signals.
3. Regulatory Requirements: In some regions, there may be restrictions on the usage of certain frequency bands for radar systems, which could influence the design choices.

A pressure transmitter with a range of 0-100 bar.The accuracy of the instrument is 1% of upper range value? The pressure indicating transmitter is showing the system pressure is 50 bar. b. When you include the error, what is the minimum possible pressure in our fuel gas system? i. 49.5 bar ii. 49 bar iii. 1 bar iv. 0.5 bar We want to change the filter cartridge. We must depressure the fuel gas system. c. After we depressure the system in preparation for maintenance, the transmitter displays a pressure of +0.1 bar. At this time, what is the possible range of pressures in our fuel system? i. +0.099 to +0.101 bar ii. 0 to +0.2 bar iii. -0.1 to +0.3 bar iv. -0.9 to +1.1 bar
