The invention discloses a signal transmitting and receiving method for cylindrical array radar imaging, and the method comprises the following steps of obtaining a target frequency point matrix according to the minimum operating frequency and the maximum operating frequency of a cylindrical array radar; and simultaneously selecting a transmitting array element in each array element set matrix as first transmitting array elements; sequentially assigning each frequency point in the target frequency point matrix to each first transmitting array element as the transmitting frequency point of the first transmitting array element, wherein the transmission frequency points of the first transmission array element in different array element set matrixes at the same time are different; transmittingsignals according to the allocated transmitting frequency points by using the first transmitting array element; and receiving the signals by the receiving array element. The signal transmitting and receiving method in the invention can reduce the number of array elements, and reduce the complexity of the cylindrical array radar device system as well as the acquisition time of the detection data onthe premise of ensuring that sufficient echo data for imaging is obtained.
Description
technical field [0001] The invention relates to the technical field of phased array radar antennas, in particular to a method and device for sending and receiving signals for cylindrical array radar imaging. Background technique [0002] In order to protect public safety and guard against various threats, security checks for people coming and going in public places, especially railway stations, airports, and passenger stations, are essential. Among many security detectors, microwave imaging is the most widely used. However, traditional security detectors cannot achieve all-round detection, so research institutions at home and abroad have turned their attention to cylindrical array radar imaging. [0003] The existing cylindrical array radar has two working methods. One is to use the transceiver antenna to perform mechanical scanning in the curved surface. Although this method has a small number of array elements and a simple system, it takes a long time to collect data and ...
