The Photographic Display Unit, or PDU, was a large-format display system used by the Royal Air Force to present radar images for interpretation by a number of operators and commanders.

The module operates entirely over the GNU Ra-dio message passing interface, packetizing each pulse received by the radar into a protocol data unit (PDU) to simplify downstream processing and minimize latency.

Description: Information about active electronic warfare (EW) emissions and active EW countermeasures shall be communicated using an Electromagnetic Emission PDU. The following information shall be provided for each system: a) PDU Header - This field shall contain data common to all DIS PDUs.

The E-8C aircraft radar looks deep into hostile areas to detect, locate, classify, and track thousands of potential targets. This radar operates in two basic radar modes: moving target indicator (MTI) and synthetic aperture radar (SAR).

Several PDUs power a turret radar system undergoing testing at the Munson test area. The PDUs provide AC and DC power to motors and peripheral controls, and include remote switching outlet control.

The PDU consisted of equipment that could record the radar image on 35 mm film, develop, fix and dry the image and then project it up on to the plotting table in the control room on the floor above. The displayed image was one minute behind real time. The PPI image from a high intensity CRT was projected on to the film through a focusing lens.

Moreover, it can send all required input for the radar as UDP PDUs. See the following figure for an overview: The signal values in a received PDU are ...

Stairs in one corner of the Operations Room led down to a basement containing the Kelvin Hughes Photographic Display Units and an associated darkroom. The PDU was required to apply a six foot diameter image of a PPI radar display to the underside of the translucent Plotting Table, and it achieved this in the following manner.
