Detection of low-contrast objects by ground-penetrating radar with controlled radiation pattern

Currently, ground penetrating radars are widely used, mainly shallow ones, based on stroboscopic oscilloscope technologies. In the specialized segment of geological exploration, deep pulsed ground penetrating radars with ultra-wideband signals of increased power are used. All these types of devices have a fixed directional diagram of antenna-feeder devices. A method for controlling the directional diagram of the transmitter antenna is proposed, which allows receiving several signals with different phase amplitude characteristics at one point without mechanical movement of the device. The development of new algorithms and methods for processing such signals will increase the possibility of detecting low-contrast objects.
