Abstract
The invention relates to a vehicle-mounted lifting rod platform applied to an anechoic chamber RCS test. The vehicle-mounted lifting rod platform comprises a vehicle chassis, a lifting rod, an orientation platform, an adjuster, a wave absorbing cover and a limiting snap ring, the lifting rod is arranged at the middle of the vehicle chassis, the orientation platform is arranged at the top of the lifting rod, the adjuster is slidably connected to the outside of the lifting rod, the wave absorbing cover is arranged on the adjuster, and the limiting snap ring is inserted on the lifting rod at thebottom of the adjuster, wherein the adjuster is located at the upper part of the lifting rod, hinge platforms are fixedly connected to four corners of the adjuster, supporting rods are hinged to the hinge platforms, the wave absorbing cover comprises a ceiling and a side curtain, the ceiling is made of a rectangular fabric, the side curtain is made of a square ring-shaped fabric, the side curtainis sewn bottom of the four sides of the ceiling, the supporting rods are fixedly connected to the bottom of the ceiling, one of the ends of the supporting rods is connected with the four corners of the ceiling, so that an end face of the ceiling is horizontal, and the side curtain covers the vehicle chassis, and a bottom end of the side curtain abuts against the ground. The vehicle-mounted liftingrod platform provided by the invention has the advantages of being able to perform large-range RCS test in a darkroom, and realize loading, program controlled lifting and rotating of a test antenna.
Description
technical field [0001] The invention relates to the technical field of testing equipment, in particular to a vehicle-mounted elevating pole platform applied to RCS testing in a microwave anechoic chamber. Background technique [0002] The high-precision test requirements of high-stealth targets force the microwave anechoic chamber to pursue the performance of the quiet zone with ultra-low background level. The existing methods for reducing the background level of the quiet zone mainly fall into two categories. Additional scattering; the other is to use the background cancellation technology to filter out the background level contribution through numerical processing. Usually, the two methods are combined to ensure the performance of the quiet zone of the microwave anechoic chamber and maintain the consistency of the background environment. [0003] The lifting platform is used to set up the test target to make the auxiliary test equipment commonly used in the microwave anech...
