The Radar dictionary contains classes that support radar observations. This class specifies the parameters for radar observations acquired from groundbased facilities. Indicates that the observations were carried out with a groundbased radar facility. Attributes that describe the dimensions of a pixel Specifies the quality of the radar observations. This class specifies the parameters for radar data. Attributes and classes for radar images Specifies the sampling properties of the radar observations. Gives pertinent radar properties with respect to the target Specifies the transmission properties of the radar used for the observations. This section contains the simpleTypes that provide more constraints than those at the base data type level. The simpleTypes defined here build on the base data types. This is another component of the common dictionary and therefore falls within the common namespace. The frequency interval from the edge of one pixel to the next in the Doppler dimension of a radar image. Specifies the total matched-filter signal-to-noise ratio in one run, expressed in db. Specifies total matched-filter signal-to-noise ratio in one run, expressed as a ratio. Type of radar experiment being performed. Simpler experiments can have higher signal-to-noise or simpler hardware configurations, while more complicated experiments provide more information. ‘Range’ and ‘Total Power’ are mostly historical. Specifies the number of pixels in an image with measurable signal. For repeating waveforms including pulse patterns, it specifies the frequency at which the waveform or pulse pattern repeats. For repeating waveforms including pulse patterns, it specifies the interval from the beginning of one waveform or pulse pattern to the beginning of the next. Range_depth_distance is the line-of-sight distance from the nearest to the farthest illuminated range element in the product. This is an indicator of the usefulness of the observation for analysis. Range_depth_time is the round-trip time delay from the nearest to the farthest illuminated range element in the product. This is an indicator of the usefulness of the observation for analysis. The distance from one pixel to the next in the range dimension of a radar image. This is commonly the same as or a multiple of range_resolution_distance. The time interval from the edge of one pixel to the next in the range dimension of a radar image. This is commonly the same as or a multiple of range_resolution_time. The minimum separation distance that can be resolved between two closely spaced targets by a radar in units of distance, based on the properties of the transmitted signal. The minimum separation distance that can be resolved between two closely spaced targets by a radar in units of time, based on the properties of the transmitted signal. Specifies the interval between the beginning of one time sample and the beginning of the next time sample for a data acquisition system Specifies the frequency at which samples repeat for a data acquisition system. Specifies whether the time samples are real values or complex value pairs obtained simultaneously for a data acquisition system. It does not imply a numeric format. Sample Type is whether the (usually voltage) samples are single real values or a complex number pair (a + ib), which depends on the hardware used. In either case, the numbers themselves can be any numeric type. In raw form, they are usually few-bit integers or pairs of few-bit integers. But they may get converted to floating point in processing. Specifies the central transmitter frequency. Specifies the transmitter power Specifies the distance from the transmitter, to the target, and back to the receiver at the time of observation, expressed as light time.
