Hi,
I am confused about the concept of transmit power and detection range
in radars, especially fmcw and pulsed systems. Can someone please give
some pointers.
As an example, contrast a fmcw radar transmitting at 1 W continuously
and a pulse radar transmitting at peak of 4 kw with a certain prf,
duty cycle.
Assuming, by some miracle, their average power is the same & there is
no difference in any other physical or processing ability, does this
mean that both these radars should detect the same target at the same
range.
Just based on transmit power variable.
How does the concept of "throwing out" equivalent energy will give
equivalent detection, factor into this?
This may be related to the above. How is it possible for fmcw radars
which transmit only 1 watt of energy to detect at such far ranges. I
have read till 40 km or so. On the other hand, my mobile phone
transmitting 1 W cant get a good connection to a clearly visible
telecom tower in the city.
Thanks
Vijay
