Light, fast & accurate, high dynamic range, low consumption level, easy to interface and trigger, time-stamping, covering a large frequency band: these are some of the most important criteria we defined for selecting the appropriate RF receivers to be integrated in our Airborne Monitoring Unit LS OBSERVER AMU.
We equip our AMU with two types of spectrum analyzers, depending on the requirements in terms of frequency range and analysis capabilities (like I/Q recording). In line with the growing demand for higher frequency bands, for example to measure microwave links, our solution to cover a frequency range from e.g. 30 MHz to 50 GHz with just ONE SINGLE receiver constitutes a real innovation and benefit.
We have of course the possibility to add additional filtering and pre-amplifying according to the type of signals to be measured.
Beside the physical and electric integration of the receivers, the performances of our AMU rely on the way we control them and how we realize the capture and analysis of the measured data: the most valuable part of our own-developed software.
The selection of antennas with a good compromise in terms of size/weight and performances, but also regarding their frequency range – in order to limit the number of antennas to be swapped on the drone – has been part of our design process.
We integrate in our AMU antennas of various technologies (log-per, horn, biconical, loop) and with either directional or omnidirectional characteristics in our AMU, depending on the selected application (spectrum scan or DF) and technology used (AoA or PdoA).
We have also designed practical fixing to allow quick position changing depending on the polarization of the signal to be measured. For some specific application like antenna measurement, the antennas can be mounted on special gimbals in order to maintain the polarization.
