**1. Introduction** The shipborne UAV system is composed of several functional components, including the aircraft platform, the measurement and control and information transmission system (referred to as the "measurement and control system"), the mission load system, the ship-based comprehensive support system, and the navigation and flight control system. As a crucial part of the shipborne UAV system, the measurement and control system enables remote control, telemetry, tracking, positioning, and information transmission for the drone. This includes the data link and the ship-based control station, with the data link comprising equipment for measurement, information transmission, and data relay. Compared to aerospace measurement and control systems, which are primarily designed for fixed-orbit aircraft outside the atmosphere, the shipborne UAV measurement and control system operates in a more complex environment due to its atmospheric flight and the challenges posed by the maritime setting. Therefore, it places greater emphasis on real-time performance, interoperability, anti-jamming capabilities, and adaptability. This paper explores the key technologies of the shipborne UAV measurement and control system by analyzing existing and emerging technologies. These include data link communication technology, ship-based measurement and control station technology, and antenna design technology. **2. Shipborne UAV Data Link Communication Technology** The shipborne UAV data link is used to transmit formatted tactical information between the ship-based measurement and control station, the command information system, and the drone, following specific communication protocols and message standards. It integrates closely with the control station, the drone system, and the command system, connecting scattered detection units and accusation systems across geospatial space. This ensures real-time, reliable, and accurate information sharing such as intelligence, command and control, and drone coordination, enabling commanders to monitor target areas in real time, reduce information acquisition time, and enhance the operational efficiency of the drone system. To meet the demands of future combat missions, UAVs face challenges in data transmission capacity, anti-jamming, security, and networking.

Current line-of-sight data links operate at speeds of 1.544 Mbps, 8.144 Mbps, and 10.71 Mbps, sufficient for general tactical reconnaissance. However, with the integration of synthetic aperture radar, airborne early warning systems, and high-resolution, multi-spectral sensors, future data rates could reach up to 3 Gbps or higher, significantly increasing the demand for data transmission capacity. To address this, research should focus on four main areas: integrated channel synthesis technology ("four-in-one" system), UAV video compression coding, and laser communication. (1) The "four-in-one" integrated channel system combines tracking, telemetry, remote control, and information transmission into a single carrier system. This allows video and telemetry signals to share a channel, either through analog frequency division or digital composite transmission. This system requires solving the challenge of high-precision automatic antenna tracking for wideband modulated signals. (2) UAV video compression coding uses the correlation within video data to remove redundant information in both spatial and temporal domains. Techniques include intra-frame, inter-frame, and entropy coding. For UAV applications, low-storage overhead, strong real-time performance, and high image quality are essential. (3) Laser communication offers much higher data rates than microwave links, with foreign systems already achieving tens of megabits per second. By 2030, shipborne UAV systems may require 500 Mbps or higher, driving advancements in optical communication systems. **2.2 Anti-Jamming Data Transmission Technology** Anti-jamming technology for UAV measurement and control systems involves spread spectrum techniques, adaptive interference suppression, and source/channel coding to ensure smooth operation. To improve anti-jamming performance, the following areas need further development: (1) Anti-jamming technology has evolved from single-layer solutions to multi-layer approaches, integrating physical, network, and application layers. It also moves from device-level to system and network-level comprehensive anti-jamming strategies. (2) Intelligent zeroing antennas use array signal processing and digital beamforming to create nulls in the direction of interference sources, achieving over 20 dB of attenuation. (3) Adaptive interference suppression techniques detect and eliminate narrowband interference using frequency-domain features of wideband signals. (4) Cognitive-based anti-jamming combines spectrum sensing, management, and link parameter reconfiguration to dynamically avoid interference and ensure reliable transmission.
