Problems solved by technology

The two ground-penetrating radars that use a single antenna have several common disadvantages: ①The electromagnetic wave radiated to the ground is basically omnidirectional, and the excitation to the detection target is weak, resulting in a shallow detection depth; ②The frequency is reduced to increase the detection depth , the contradiction between detection depth and longitudinal resolution cannot be well resolved
③ Poor horizontal resolution
④ Small amount of information

Abstract

The transmission scanning phased array geologic prospecting radar is formed from the components of radar main machine, emission antenna array, multi-channel transmitter, receiving antenna array, multi-channel receiver, front-end integrated controller and portable integrated industrial control computer. Said invention also provides the concrete structure of the above-mentioned every component and their connection mode.

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...
