Description

technical field

[0001] The invention relates to the technical field of ground-penetrating radar, in particular to a multi-channel ultra-wideband array ground-penetrating frequency array radar system and a control method. Background technique

[0002] Ultra-wideband radar technology uses the electromagnetic difference of the underground medium to detect buried targets. During the propagation of electromagnetic waves in the underground medium, when encountering underground targets with electrical differences, such as holes, water, and interfaces, the electromagnetic waves will be reflected. Or scattering, the radar control system performs signal processing and analysis on the received electromagnetic waves according to the parameters such as the amplitude, delay, shape and spectrum characteristics of the received echo signal, and can interpret the target depth, medium structure and properties, so as to complete the covert target imaging and recognition.
