AbstractThe Meteor and ionospheric Irregularity Observation System (MIOS), which consists of multi-station optical subsystem at Ledong (18.4 degrees N, 109 degrees E) and Sanya (18.3 degrees N, 109.6 degrees E), and radar subsystem including a 38.9 MHz all-sky interferometric radar and a 47.5 MHz coherent phased array radar at Ledong, has been in full operational since December 2021. This paper describes the system design and first results of meteor plasma density irregularities and corresponding meteoroids. The MIOS optical subsystem consists of a few tens of video cameras for observing optical meteor trail and spectrum. The MIOS phased array is composed of 135 Yagi antennas, arranged in sword-like grid and grouped into 15 identical subarrays, with distances separated by 2-19.5 times the wavelength for unambiguous interferometry measurements. The phased array can form narrow and wide beams, with half power width of 8 degrees and 24 degrees in azimuth, respectively, allowing narrow-beam pulse-to-pulse steering and wide-beam multi-baseline imaging observations in the east-west direction. Observational results show that the MIOS is capable of unambiguously locating various meteor echoes, that is, head, specular and non-specular echoes, revealing the structural evolution of field-aligned and non-field-aligned irregularity, and of determining the properties of meteoroids producing/not producing irregularities. Cases of bright meteors producing non-field-aligned irregularities and not producing field-aligned irregularities respectively are presented, and possible factors affecting the generation of meteor trail irregularities are discussed based on current understanding. It is expected that the MIOS will provide an important tool to study the generation and evolution of various meteor trail irregularities and the properties of the corresponding meteoroids.
