Hypocenter positioning system

Abstract

The invention discloses a hypocenter positioning system. A nuclear electromagnetic pulse signal is transmitted to a signal processing unit; the signal processing unit is connected with a sensor array unit through a signal transmission line; the sensor array unit comprises three or more shock wave receiving sensor arrays; the signal processing unit is used for recording the arrival time of the nuclear electromagnetic pulse signal and the wave arrival time of each shock wave receiving sensor; and the coordinate of the hypocenter is calculated according to the difference between the arrival time of the nuclear electromagnetic pulse signal and the wave arrival time of each shock wave receiving sensor in combination with a coordinate in a three-dimensional coordinate system of each shock wave receiving sensor. Through the way, single-station full-automatic hypocenter positioning can be realized without being influenced by visibility, the detection distance is long, the coordinate of a hypocenter is calculated by using know conditions with a mathematic algorithm, the detection error is small, and the positioning accuracy is high.

Description

technical field [0001] The invention relates to the field of explosion center detection, in particular to an explosion center projection point positioning system. Background technique [0002] Monitoring the explosion time and the position of the projection point of the blast center provides a basis for estimating the instantaneous damage, predicting the radioactive contamination of the ground and the air, and providing a basis for planning the consequences of the attack. [0003] The original single station uses the steering wheel and electromechanical goniometer to measure the angle. These types of angle measuring devices must be operated by personnel. When measuring the distance, the nuclear electromagnetic pulse arrival time is used as the nuclear explosion time, and the shock wave arrival time is used as the shock wave running time.

Problems solved by technology

These types of angle measuring devices must be operated by personnel. When measuring the distance, the nuclear electromagnetic pulse arrival time is used as the nuclear explosion time, and the shock wave arrival time is used as the shock wave running time. When calculating the blast center distance by measuring the shock wave arrival time, it is necessary to consider The influence of factors such as nuclear explosion equivalent, wind direction, wind speed, air temperature, air pressure, and atmospheric non-uniformity is used to correct the shock wave running speed. The actual shock wave speed is an estimated value, so the distance error is relatively large
