Abstract: An embedded heat dissipating device mounting structure including a housing for an electronic instrument, the housing having an opening and two parallel side boards perpendicularly raised from the periphery of the opening at two opposite sides, a heat dissipating device mounted in the opening of the housing and secured to the parallel side boards and operated to carry heat out of the housing, the heat dissipating device having a cover shell which has backward springy hooks adapted for hooking on the parallel side boards of the housing at an inner side, and elongated flanges adapted for stopping against the parallel side boards of the housing at an outer side.

Abstract: A multistatic radar signature measurement apparatus comprising a curvilin sensor array of photonic sensors which are used to measure the radar cross section of a target. The array of photonic sensors provide for the simultaneous collection of target scattered measurement data over an approximately semi-spherical field of view. Laser light passing through each photonic sensor of the sensor array is modulated by the photonic sensor in direct proportion to the strength/intensity of scattered waves from the target as the scattered waves pass through each photonic sensor of the sensor array. The modulated light from each sensor of the sensor array is then transmitted to an optical switching network which samples the optical signals from the array. The sampled optical signals are next provided to an RF receiver which converts the sampled optical signals to equivalent RF electrical signals.
