The XENTA-M (variants M3 and M5) from Weibel Scientific (Denmark) is a 3D surveillance radar in the X-band with FMCW processing and an electronically steered transmit beam (digital array) for short-range air defence. It also tracks small drones in environments with interference and in formations. It can be used stationary or vehicle-mounted and is designed for military purposes.
The radar covers 360 degrees in azimuth and 60 degrees in height. The M3 draws 120 W and has a nominal instrumented range of 60 km, the M5 draws 240 W and reaches 75 km; the current product description lists the M5 in High Power and Low Power modes. These ranges are instrumented ranges for large targets, not detection ranges for drones; those are far lower and depend on radar cross section. The operating range runs from −32 to +49 °C, and the build follows MIL-SPEC.
Radars transmit too: in Germany every use of a frequency needs an assignment from the Bundesnetzagentur (Section 91(1) TKG). How frequency use is regulated in Poland has to be clarified with the competent authorities before deployment. The radar detects and tracks; jammers may be operated only by authorities in Germany and Poland (Section 91 TKG, Article 42 of the Polish Electronic Communications Law). MIL-SPEC describes ruggedness to military standards, not an approval for civil operation.
In selection, separate the air picture from drone detection: anyone looking mainly for small drones turns to the XENTA-C1/C3 series, which the manufacturer lists for pure drone detection. The 60 km or 75 km is no planning figure for drones. At 120 W to 240 W of power draw, power supply and cooling count; in a vehicle, vibration and tilt calibration come on top. Connectors, seals and the firmware version need checking. Cameras and RF detectors complement identification.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Ask about parts availability for this build year — the running costs hang on it.
