The invention discloses a Ka array receiving module, belongs to the field of measurement and control for high-dynamic flying targets. According to the technical scheme of the module, the design of both multi-beam multi-feed-source antennas and a Ka multi-channel receiving module is required. The Ka array receiving module consists of a 14*16 multi-beam feed-source array, a change-over mounting plate, a Ka active switch frequency conversion unit array and the like, wherein the multi-feed-source antennas can realize the 3*3 beam coverage range through 208 paths of beams; the Ka active switch frequency conversion unit array can receive 208 paths of Ka signals; after down conversion, the signals are processed by a baseband; the baseband can complete one-time whole-space signal capture in the beam coverage range within 3 ms by adopting an advanced multi-beam signal energy detection technology. The Ka array receiving module is mainly used for providing support for application of rapid angle capture of high-dynamic targets.
Description
technical field [0001] The invention relates to a multi-beam feed Ka array receiving component technology in the field of measurement and control of high dynamic flying targets, in particular to a Ka array receiving component suitable for fast acquisition of high dynamic flying targets under low signal-to-noise ratio. Background technique [0002] The development of measurement and control systems is very rapid, and the demand for use has increased dramatically. The current measurement and control system mainly adopts the USB system S-band measurement and control network. The USB system cannot meet the new requirements of high-speed data transmission, higher orbit measurement accuracy, and anti-interference in the field of measurement and control due to its low operating frequency band and narrow operating frequency bandwidth. development bottleneck. Contents of the invention [0003] The purpose of the present invention is to avoid the shortcomings in the above-mentioned...
