Record number: 2, Textual support number: 1 OBS

Scaling refers to conversion of the image matrix without changing the image contents. The digital matrix-oriented projectors and monitors often have a different natural resolution to that of the image signal. The process required to adapt the image from a video signal to a graphics card signal, e. g. 1024 x 768 pixels, is called video scaling.  4, record 2, English, - video%20scaler

A "RAW Signal Data" product contains raw or unprocessed radar video baseband data in complex in-phase and quadrature signal(I and Q) format as they are recorded by the spacecraft. The only processing performed to the downlink X-band "raw signal data" is the frame synchronization, meaning re-assembly of the data into contiguous radar range lines in matrix form, and the CEOS [Committee on Earth Observations Satellite] formatting. Each range line of data is represented by one Signal Data Record in the RAW CEOS product.  2, record 4, English, - %5C%22raw%20signal%20data%5C%22%20product

The RAW product can contain any single beam mode, or for ScanSAR any combination of different beam modes, depending on the operation of the SAR instrument during the data reception or recording period. A RAW product cannot, however, combine data from more than one beam mode, i.e. data from two different beam modes are always packaged as two separate products. A RAW product must be SAR processed before it can be displayed as imagery. RAW products are typically produced on 8 mm (Exabyte) tapes. This is the standard medium for exchanging data between network stations.  2, record 4, English, - %5C%22raw%20signal%20data%5C%22%20product

A covariance matrix is generated using the echo returns. The presence of at least one target within a single range cell is detected. A plurality of consecutive pulses are transmitted in a direction of the single range cell within a sufficiently short period so that at least one target remains within the single range cell while the plurality of consecutive pulses are transmitted. An echo signal is sampled from each of the plurality of pulses. An updated covariance matrix is estimated each time the echo signal is sampled. An eigenvalue decomposition is updated each time the covariance matrix is updated. The number of targets in the single range cell is estimated, based on the updated eigenvalue decomposition.  2, record 5, English, - covariance%20matrix

The main units of the AIC are : the focal plane assembly(FPA), equipped with a back-thinned illuminated CCD matrix and a front-end amplifier, provides the optical signal detection. A thermoelectric peltier cooler under the detector sets the operating point at-25°C ± 100 mK, the detection box(BD) which supplies the FPA with the necessary electrical signals to operate the CCD. It generates the clock waveforms from the VEU signals and filters the supplied voltage from the DSU, the video electronics unit(VEU) which processes the analog signal coming from the FPA, digitizes it on 12 bits before passing it on in serial processing to the science data processing subsystem(SDPSS). It also provides the DBs with the primary clock signal. The power conditioning of the VEU is located in the same unit, the detection supply unit(DSU) delivers relevant stabilized voltages to the 5 DUs and power to thermo-coolers from the main supply feeder of the instrument.  2, record 6, English, - analog%20imaging%20chain

In facsimile, the diode sensor array uses a stationary configuration of tiny photodiodes arranged in a matrix that equals in width one lateral scan line of a document. An original is rollerfed from a flatbed tray and passes by the sensor array one line at a time. Light is reflected from each line and focused through a lens onto the face of the photodiode array. Each diode acts as an independent photosensor in converting a small picture element into part of the total electrical signal for a scan line.  1, record 9, English, - photodiode%20sensor%20array%20scanner

The signal designated M conveys luminance information; it is nominally equivalent to the signal that would be generated by a monochrome camera viewing the same scene as the color camera. That is, the M or luminance signal controls the sensation of brightness.  4, record 10, English, - encoder
