In the paper, a model of a detector of high-speed microparticles (micrometeoroids and space debris) is proposed, made in the form of a round spiral film inductance coil. The design of the gauge ensures the creation of frequency resonance that occurs when the metal strip of the coil is broken. The obtained results of a laboratory and computer simulations of the detector showed that the film coil is suitable for recording high-speed microparticles larger than 100 μm on a spacecraft such as CubeSаt. The fracture point of the inductance coil can be found by analyzing the shift of the resonant frequency of the amplitude-frequency characteristic. In this case, the reliable determination of the point becomes possible if the number of the broken turn is greater than 5.
