In recent years, the Resident Space Objects in Low Earth Orbit (LEO) have been dramatically increased due to space activities which may cause the risk of collision by its large populations. Thus, Space Traffic Management (STM) is a significant solution to space technology development as it guarantees safety. Radar sensor systems have emerged as pivotal tools for space objects monitoring. LeoLabs is a commercial provider of space object detection and monitoring services, operating via their global distributed radar network. Their space radar network system, which consists of Phased-array radars, serves as a measurement tool for space services related to STM in LEO, including tracking and mapping space objects, issuing real-time conjunction alerts, and supporting spacecraft launches. This system presents various noteworthy aspects at both individual radar sites and the network cooperation scale. Hence, this article is going to introduce the LeoLabs radar information from our literature review which includes overall system architecture, briefly radar sites information, system performance, etc.
