Research progress on electromagnetic characteristics of plasma generated by hypervelocity impacts

The paper presents the state of researches on the electromagnetic characteristics of hypervelocity impact produced plasma abroad. Electromagnetic characteristics of plasma generated by hypervelocity impact include electron temperature, particle density and oscillation frequency of plasma, and magnetic fields. Characteristic parameters were diagnosed by using sweep Langmuir probe system, coil systems for magnetic induction intensity measurement. The electromagnetic characteristics of plasma generated by hypervelocity impact were analyzed.
