1. Product Overview
The multi-target telemetry receiving antenna can automatically and independently align with four telemetry targets within a 200 MHz bandwidth. Utilizing a digital two-dimensional multi-beam horizontal turntable scheme, it can achieve electronic scanning within a 90-degree horizontal/elevation range and mechanical scanning over a 360-degree horizontal range, thereby enabling simultaneous detection, tracking, and telemetry tasks for multiple targets in different azimuths. The monitoring and management host software can realize real-time display and monitoring of multiple telemetry targets, meeting the future needs of measurement and control systems for multi-target, digital, flexible, and reliable operations, and possesses promising application prospects.
