A new diagnostic tool for space plasmas is presented. The oblique resonance excited by an antenna in a magnetoplasma has been detected in the ionosphere with a rocket experiment. The instrument is simple and consists of a fixed frequency transmitter and a receiver. The resonance cone and its fine structure are used to deduce the plasma density and the electron temperature. The possibility of measuring field‐aligned currents is briefly discussed.
