The invention discloses a millimeter wave receiving and transmitting system based on sparse array and module multiplexing. The millimeter wave receiving and transmitting system comprises a frequency agility source, a receiving and transmitting channel and two antenna feeder assemblies. The transceiving channel comprises a frequency conversion assembly, a transmitting single-pole eight-throw switchmodule and a receiving single-pole four-throw switch module. Each antenna feeder assembly comprises a transmitting channel and a receiving channel, and the transmitting channel comprises four transmitting horn antennas; and the receiving channel comprises two single-pole 16-throw switch modules integrated with receiving horn antennas. The transmitting channels of the two antenna feeder assembliesare connected with the frequency conversion assembly through the transmitting single-pole eight-throw switch module. Compared with an existing full-array receiving and transmitting system, the systemof the invention has the advantages that a sparse array combined module multiplexing system is adopted, so that the hardware cost of the transceiving system is greatly reduced; and the scheme is simple, and the power consumption is low.
Description
technical field [0001] The invention relates to the technical field of object detection, in particular to a millimeter wave transceiver system based on sparse array and module multiplexing. Background technique [0002] In recent years, millimeter-wave near-field imaging systems have been widely used, and the main application fields are human security inspection and object detection. At present, the commonly used technical systems are mainly divided into two types: "two-dimensional sparse array" and "one-dimensional Linear array + one-dimensional mechanical scanning", the "two-dimensional sparse array" technology system is represented by Rohde & Schwarz, companies using the "one-dimensional linear array + one-dimensional mechanical scanning" technology system mainly include American L3 companies, domestic Bowei Terahertz, Nuctech and ECCOM Ark. [0003] The terahertz millimeter-wave active imaging system has received extensive attention in the field of security inspection a...
