Question

The biggest disadvatage of cw doppler radar is that give

Answer 1

Answer:

ompared to the coaxial lines waveguides have significant advantages. But in practice, these advantages can be used only at frequencies higher than 1 GHz effectively. They have several advantages over two-wire and coaxial transmission lines. The main advantage is that waveguides support propagation with lower loss.

Answer 2

Answer:

Limitations. Continuous wave radar with no modulation cannot determine distance.

Explanation:

CW Doppler radar:

Continuous-wave radar (CW radar) is a type of radar system where radio radiation with a known steady frequency is sent and subsequently picked up by any reflecting objects.

What is the CW Doppler radar's main drawback?

Problems with CW Doppler Radar:

The greatest range of the CW radar is constrained by its power. The receiver sensitivity is impacted by the degree of isolation and transmitter noise, which determines maximum power. The CW Doppler radar is unable to determine the target range.

• The power that radar can emit determines the maximum range of CW Doppler radar.
• CW Doppler radar cannot determine the target range.
• The risk of unclear findings exists when there are more targets.

hence Limitations. Continuous wave radar with no modulation cannot determine distance.
