The invention discloses a miniaturized ranging module based on self-adaptive cancellation technology. The miniaturized ranging module is equipped on a detonation control system to realize real-time height measurement and output proximity detonation instruction at the predetermined height; the module comprises an external interface, a power supply interface connecting line, a communication data connecting line, a denotation control instruction output line, a JTAG debugging interface, a power conversion circuit, a serial port communication control circuit, a Flash storage chip, a FPGA chip circuit, a SPI bus line, an A / D sampling circuit, a D / A conversion circuit, an integrated microwave transceiving circuit, a first receiving antenna, a second receiving antenna and a transmitting antenna; alinear frequency-modulation continuous wave detection system is adopted, the module is worked at the millimeter band, and the miniaturization is realized by adopting the integrated microwave chip, the volume is reduced to 1 / 20 of the traditional ranging module; on the basis of the miniaturization design, the near-distance dead zone is reduced to 2m by adopting the self-adaptive cancellation technology; and the module has the characteristics of being high in precision, high in reliability, small in volume, and strong in interference resistance.
Description
technical field [0001] The present invention relates to the technical field of detonation control systems, in particular to a miniaturized ranging component based on adaptive cancellation technology that is equipped with a detonation control system for real-time height measurement and outputs near-detonation detonation control commands at a predetermined height. Background technique [0002] In the detonation control system, it is generally necessary to be equipped with a ranging component, so as to realize real-time height measurement, so as to output a near-explosion detonation instruction at a predetermined height; and the existing ranging components used in the detonation control system are generally large in size and not It is beneficial to the overall miniaturization of the detonation system; at the same time, the existing ranging components have a large short-range blind area, and there are problems of small anti-interference dynamic range, poor anti-interference abili...
