Exemplary aspects are directed to or involve a radar transceiver to transmit signal and receive reflected radar signals via a communication channel. The exemplary method includes radar receiver data processing circuitry that may be used to differentiate a subset of representations of the received signals. This differentiation may be used to select signals that are more indicative of target(s) having a given range than other ones of the received signals. The received signal's representations may then be compressed by using variable-mantissa floating-point numbers having mantissa values that vary based, at least in part, on at least one strength characteristic of the respective representations.

The output includes weather information based on the received weather data. The processor-executable code causes the processor to receive a user input from a user interface element of the aircraft where the user input requests updated weather information.

A computer-implemented method executed by one or more satellites for assessing crop development by using synthetic aperture radar (SAR) is presented. The method includes generating SAR images from scanning fields including crops, monitoring grown of the crops within the fields during a predetermined time period, and estimating a height of the crops during the predetermined time period by using interferometric information from one or more of the SAR images and tracking change in height and growth rates.

A vehicle environmental detection system (3) in an ego vehicle (1) including at least one control unit arrangement (15) and at least one detector arrangement (4, 7) that is adapted to obtain a plurality of detections (14). The control unit arrangement (15) is adapted to form a cluster (40) of the plurality of detections (14), form a first border line (16) and a second border line (17), where these border lines (16, 17) have mutually longitudinal extensions, and are mutually parallel and define outer borders of the cluster (40) and determine whether the cluster (40) corresponds to a row (13) of corresponding parked vehicles (18a, 18b, 18c, 18d, 18e, 18f, 18g), by the length or longitudinal displacement of, or distance between, the border lines (16, 17).

According to the method, a radar signal is transmitted from the at least one radar transmit element to the target object, and signals being reflected by the target object are received at the receiver channels. A frequency transformation of the reflected signals is performed in order to create a range-Doppler map for each of the plurality of receiver channels. Furthermore, a beam vector is generated by selecting a respective value from each of the range-Doppler maps as an element of the beam vector corresponding to a respective receiver channel. The beam vector is processed by a Fourier transform and a peak amplitude from the Fourier transform is calculated. Finally, a reference value is calculated which depends on the elements of the beam vector, and the peak amplitude is compared with the reference value in order to determine the extent to which the target object is a single point scattering center.
