Time Domain High Current Aeronautical Electromagnetic Transmitter

Abstract

The invention discloses a time-domain heavy-current aviation electromagnetic emission apparatus. The apparatus comprises a control module and a large-power main loop module, wherein the large-power main loop module comprises an LC resonance full-bridge inversion major loop and a constant-power charge major loop, the LC resonance full-bridge inversion major loop comprises capacitors and an emission coil, the control module controls the constant-power charge major loop to charge the capacitors, after charging is completed, the capacitors supply electric energy to the emission coil, emission currents are generated in the emission coil, after discharging of the capacitors is finished, the control module controls the emission coil to reversely charge the capacitors so as to recover and utilize residual electric energy of the emission coil, and after the electric energy of the emission coil is completely discharged, the constant-power charge major loop continuously charges the capacitors, such that residual electric energy resources are saved, the weight of the time-domain heavy-current aviation electromagnetic emission apparatus is reduced, and the purpose of large-magnetic-moment emission is realized.

Description

Technical field [0001] The invention relates to the field of aviation detection, and more particularly to a time domain high-current aviation electromagnetic launch device. Background technique [0002] The time domain airborne electromagnetic exploration system (ATEM) is one of the airborne geophysical methods. ATEM's transient electromagnetic exploration system mounted on the aircraft platform realizes rapid detection and identification of underground resources through flight operations. It has the characteristics of low cost, high speed, and good mobility. It can be used for complex terrain, surface vegetation, Rapid assessment of resources in target areas in such coverage areas as deserts, and large-scale resource surveys. The time-domain aerial electromagnetic survey system uses an ungrounded power supply (coil), which can increase the survey depth and improve the data quality by directly increasing the launch magnetic moment. The time-domain airborne electromagnetic explo...

Problems solved by technology

According to the above transmission mode, the transmitter outputs higher power at intervals. If the power provided by the power supply is directly used for output, there is a problem of insufficient equipment utilization.

Transmitting antennas generally use wires to wind coils, and their external electrical characteristics are equivalent to inductance. When transmitting pulse currents to inductive loads, there is a problem of residual energy recovery.
