A system for pinpointing CDP sources in a two-way HFC CATV network comprises a headend CPD radar unit, a return path switch, and a computer. The radar unit is coupled to a headend combiner. The return path switch is coupled between the nodes of the CATV network and the radar unit. The computer is connected to the radar unit and the return path switch. The computer controls the radar unit and switch and causes them to perform constant sequential CPD monitoring of the nodes of the network. The system further comprises a portable radar-calibrator unit that is carried into the field and connected to various points along the coaxial cable portion of the network. The portable radar unit is used to detect CPD sources in the field and to calibrate the network as to time delay. The portable unit communicates with the headend radar unit through the CATV network.

The invention discloses a large-area reverse coil embossing shaping method for using flexible substrate and macro electron to produce middle micro structure. The invention uses reverse coil embossing technique, relative chromatograph aligning technique, and ultraviolet solidifying technique, to produce large-area three-dimension functional micro structure needed by macro electric appliance. The invention eliminates the left membrane in general embossing, to eliminate the additional process needed for treating left membrane. And the invention adds optical solidifier in electric functional material to solidify cold ultraviolet light source, thereby reducing the thermal deformation of flexible material. The invention has wide application in the productions of macro electron system as expandable large-size display, electric paper, OLED, film RFID, flexible solar sail, portable X-ray imager, portable radar, space solar power system, antenna device, and electromechanical intelligent cover adhered on the surface of arbitrary three-dimension structure.

An airborne wind profiling portable radar (AWiPPR) system comprising a mobile airborne platform including one or more navigation units configured to produce navigation data including at least the position and orientation of the mobile airborne platform. A radar unit is mounted and positioned to the mobile airborne platform, the radar unit is configured to transmit a wide-band frequency modulated continuous wave radar signal in a downward direction from the mobile airborne platform towards the ground and configured to continuously receive a reflected signal from a plurality of clear air scatters (CAS) targets or volumetric targets and output radar data. An inertial measurement unit (IMU) in communication with the one or more navigation units and the radar unit is configured to receive the navigation data and determine the position and orientation of the radar at a specific point in time and output IMU data. A data acquisition unit in communication with the radar unit and the IMU is configured to receive and time align radar data and the IMU data for each reflected signal from each of the plurality of CAS targets or volumetric targets to provide an antenna pointing direction for each received reflected signal. The data acquisition unit is configured to process the time aligned radar data and IMU data to determine a distance and a Doppler velocity of each of the plurality of CAS targets or volumetric targets, provide a range, a velocity, and an antenna pointing direction for each of the plurality of CAS targets or volumetric targets, and calculate a vector wind velocity using the range, the velocity, and the antenna pointing direction for each of the plurality of CAS targets or volumetric scatters targets. The data acquisition unit may be configured to further correct the range, the velocity, and / or the antenna pointing direction of each of the plurality of CAS targets or volumetric targets to accommodate for a motion shift in data produced by one or more of: a relative motion and orientation of the mobile airborne platform, a Doppler spread in the range, the velocity and / or the antenna pointing direction, and a ground echo.
