A radar-based fill-level measuring device that operates, for example, according to the FMCW principle or the pulse time-of-flight principle comprises a temperature sensor. Thus, the measurement rate at which the fill level is determined can be controlled according to the measured temperature in such a way that, at least above a defined limit temperature, the measurement rate is reduced as the temperature increases further. Furthermore, the measurement can be completely stopped if the measured temperature exceeds a predefined maximum temperature, in particular 150° C. The development of heat in the fill-level measuring device is counteracted by the reduction of the measurement rate. The measurement rate is thereby adaptively adjusted with respect to the ambient temperature such that, even at elevated ambient temperatures, which can occur in the case of cleaning processes, the fill-level measuring device remains at least conditionally fit for use.

A system and a method for generating a subterranean map with ground penetrating radar are described. The system includes multiple ground penetrating radar transmitters, multiple ground penetrating radar receivers, and a controller. A first subset of the transmitters radiate a first signal at a first frequency bandwidth, a second subset of the transmitters radiate a second signal at a second frequency bandwidth different than the first frequency bandwidth, and a third subset of the transmitters radiate a third signal at a third frequency bandwidth different than the first and second frequency bandwidths. The receivers receive a first return signal at the first frequency bandwidth, a second return signal at the second frequency bandwidth, and a third return signal at the third frequency bandwidth and transmit the return signals. The controller operates the ground penetrating radar transmitters, receives the return signals, and generates a subterranean map from the return signals.

A method for exposure level estimation, includes transmitting radar signals for object detection and communication signals for wireless communication operations. The method also includes identifying a location of an object relative to the electronic device within a first time duration based on the radar signals, the first time duration including a previous time until a current time. The method further includes determining a radio frequency (RF) exposure measurement associated with the object based on the location of the object over the first time duration. Additionally, the method includes determining a power density budget over a second time duration based on a comparison of the RF exposure measurement to an RF exposure threshold, the second time duration including the current time until a future time. The method also includes modifying the wireless communication operations for the second time duration based on the power density budget.

Many different types of systems are utilized and tasks are performed in a marine environment. The present invention provides various configurations of castable devices that can be operated and/or controlled for such systems or tasks. One or more castable devices can be integrated with a transducer assembly, such as a phased array, that emits sonar beams and receives sonar returns from the underwater environment. Processing circuitry may receive the sonar returns, process the sonar returns, generate an image, and transmit the image to a display.

Technologies for calibrating radars and tracking space objects. Some of such technologies enable a technique for calibrating a radar based on using -A- an elemental antenna (308), which can be embedded on a housing hosting a set of antenna elements, or -B- an antenna (146) mounted to a reflector. Some of such technologies enable a radar site containing a first 1D phased array (112) and a second 1D phased array (112), where the first 1D phased array sends a set of signals and receives a set of reflections based on the set of signals, and the second 1D phased array receives the set of reflections.

An apparatus includes an extendable wand, and a sensor head coupled to the wand. The sensor head includes a continuous wave metal detector (CWMD) and a radar. When the wand is collapsed, the wand and the sensor head collapse to fill a volume that is smaller than a volume filled by the sensor head and the wand when the wand is extended. Frequency-domain data from a sensor configured to sense a region is accessed, the frequency-domain data is transformed to generate a time-domain representation of the region, a first model is determined based on the accessed frequency-domain data, a second model is determined based on the generated time-domain representation, the second model being associated with a particular region within the sensed region, and a background model that represents a background of the region is determined based on the first model and the second model.
