Abstract

The invention provides an ultra-wideband pseudo-random encoding radar system. According to the system, a signal output from a transmitting channel is divided into two signals; one encoded signal is transmitted out by an antenna; the other encoded signal is directly acquired by a first receiving channel as a reference signal for use in pulse compression. Therefore, the fact that the two signals are generated and acquired at the same temperature can be guaranteed, uniformity of the two signals is guaranteed, post-pulse-compression peak-to-sidelobe ratio is increased, and the system has a wider detection range and higher detection probability.

Description

technical field [0001] The invention relates to the technical field of radar in the electronic industry, in particular to an ultra-wideband pseudo-random coding radar system. Background technique [0002] In recent years, ultra-wideband radar technology has attracted much attention in the scientific and engineering circles, especially in the fields of anti-terrorism, ground exploration, technical reconnaissance, military, search and rescue, security inspection, medicine and other fields. UWB technology is a radar detection method capable of good resolution and depth of penetration for non-intrusive detection and imaging of moving targets hidden behind walls. In recent years, it has attracted much attention because of its wide application in the fields of anti-terrorism and disaster relief. [0003] At present, most ultra-wideband pseudo-random coding radars are in the stage of laboratory development. In actual engineering, the radar is required to have a large time-bandwid...
