SUMMARY

Ultra Wideband (UWB) RADAR systems operate within a frequency range of 3GHz to 10GHz, making them challenging to detect with conventional devices. Standard spycam detectors, which typically operate between 1.2GHz and 5.8GHz, can only detect some UWB signals but not their applications. Detection requires proximity to the transmitter, and interference from other devices like Wi-Fi and microwaves complicates the process. Effective monitoring of UWB signals necessitates specialized equipment and knowledge of the technology.

Ultra Wideband (UWB) RADAR systems discharge signals over a broad range of frequencies which is between 3GHz to 10GHz as compared to the conventional RADAR systems and remain extremely difficult to detect.

Will the normal spycam detector be able to detect the presence of UWB signals penetrating through the common wall?

YES, to some of the UWB signals, and NO, to what the signals are being used for.

Spycam cannot detect all of the band from 3GHz to 10GHz.
Spycam detects only from 1.2GHz to 5.8GHz.

There is so much Wi-Fi about, that you will detect signals reflected off all sorts of scatterers, wherever you look. You will also detect mobile phones and microwave ovens operating in your vicinity.

You would need to be within a metre or two of a transmitter to detect and move in on it. If it was on the other side of a property wall, you would not know what it was being used for, unless you gained access to that space, and found the rack of computers, radio equipment, and antennas, needed to implement UWB radar.

Thank you Baluncore for the answer.

with many high-tech boards easily available, a person with an EEE background can easily assemble a few Arduino-embedded systems concealed under some fixtures on the ceiling (e.g. clock, decorative..), monitoring the movement of the occupant living above it becomes very difficult to prove the intrusion.

Movement detectors, based on microwave reflection, are trivial, and cost less than $5.
A UWB movement detector, that detects only range, is also simple.

UWB radar is very complex because it must track range and direction to several moving objects, through walls made of different materials.

It takes four people to monitor the activity of one person. It is usually not worth the effort, since it is more efficient to eliminate the threat from the situation.
