Abstract

The invention relates to an ultra-wideband pulse signal transmitting device and an ultra-wideband pulse radar system. The ultra-wideband pulse signal transmitting device comprises a pulse signal generating module, which is used for generating ultra-wideband pulse signals with a certain number of single pulses; a driving module, which is used for amplifying the ultra-wideband pulse signal; a poweramplifying module, which is used for amplifying the power of the ultra-wideband pulse signal subjected to signal amplification to generate a transmitting signal; and a switch control module, which isused for controlling the driving module and the power amplification module to be switched off in a preset time period. The ultra-wideband pulse signal transmitting device adopts an ultra-wideband pulse signal generating circuit realized by an all-digital logic circuit, and only generates transient power consumption in the working process without direct current power consumption, so that the powerconsumption of the system can be obviously reduced.

Description

technical field [0001] The invention belongs to the technical field of electronic circuits, and in particular relates to an ultra-wideband pulse signal transmitting device and an ultra-wideband pulse radar system. Background technique [0002] Ultra-wideband pulse radar is a time-domain imaging detection system that works under the nanosecond pulse system. It has a wide range of applications in the fields of short-distance high-precision ranging and positioning, non-contact medical monitoring, and wall-penetrating detection. The application of CMOS (Complementary Metal Oxide Semiconductor, Complementary Metal Oxide Semiconductor) technology can significantly reduce the size and power consumption of ultra-wideband pulse radar, meet the characteristics of portable and long battery life, and attract more people's attention. [0003] Generally speaking, ultra-wideband pulse radars used in wall-penetrating detection, etc., require a higher transmission power, generally above 15dB...
