Description

technical field

[0001] The invention relates to a transmitting and scanning phased array ground-penetrating radar, which belongs to the field of radar ground (down) observation technology. The electromagnetic wave energy of the ground interferes and synthesizes a highly directional beam, and uses the "phase difference" given to each antenna unit (realized by a delay circuit) to make the synthesized beam scan quickly. When receiving, the array signal processing technology is used to compensate the amplitude and phase of each channel signal of the receiving array, so that the receiving array has the same directivity as the transmitting array. Through the above process, rapid scanning and detection of the underground is realized. Background technique

[0002] Most of the existing ground-penetrating radars are designed in the form of single-antenna transmission and single-antenna reception, and there are also a small number of single-antenna transmission and multi-antenna recep...
