400M Instantaneous Bandwidth Signal Generator: The Future Core of Counter-UAS Systems
Introduction
Recently, Embraer announced that its A-29 Super Tucano aircraft will enhance its Counter-Unmanned Aerial Systems (C-UAS) capabilities in the second half of 2026. This news once again highlights the urgent global demand for efficient C-UAS solutions in the face of growing drone threats. From reconnaissance and surveillance to attack delivery, drone technology is rapidly evolving, posing severe challenges to military and civilian security, necessitating continuous upgrades to defensive countermeasures.
Industry Challenges & Pain Points
Currently, drone threats exhibit trends of diversification and complexity. From small commercial drones modified as improvised explosive device delivery platforms to military-grade UAVs with advanced communication and navigation capabilities, their flight altitude, speed, and signal characteristics vary. Traditional counter-drone methods, such as fixed-frequency jammers or single-mode defense systems, appear insufficient when facing wideband, frequency-hopping, swarm, or even AI-assisted drones. These traditional devices often struggle to provide effective suppression due to narrow frequency coverage, slow response times, or inability to handle multiple targets simultaneously, leading to vulnerabilities in defense systems.
The Core Countermeasure: Why Signal Interference Source is Key
In complex Counter-Unmanned Aerial Systems (C-UAS) battlefield environments, one of the most core and effective countermeasures is the “Signal Interference Source”. By actively emitting interference signals, it can cut off the communication link between drones and their operators, suppress their GPS/GNSS navigation signals, and even interfere with their flight control systems. To achieve efficient interference, the key lies in having wideband coverage capability and frequency agility characteristics. Only by covering a sufficiently wide frequency range can various working frequency band drones be addressed; and only with instantaneous wideband interference capability can complex communication modes like frequency hopping and spread spectrum be effectively suppressed, ensuring drones cannot evade interference.

FAQ
Question 1: Why is instantaneous bandwidth important for counter-UAS?
Answer 1: The larger the instantaneous bandwidth, the wider the frequency range that can be covered simultaneously, leading to better interference effects against complex drone signals such as frequency hopping and spread spectrum, and faster, more effective threat suppression. This allows counter-UAS systems to more effectively respond to the diverse communication methods of modern drones.
Question 2: What are the advantages of the 400M Instantaneous Bandwidth Signal Generator’s software tunable feature?
Answer 2: Software tunable allows the system to dynamically adjust interference frequencies and modes based on real-time threat situations, greatly enhancing the system’s adaptability and capability to counter various unknown threats. It enables the system to intelligently respond to different types of drone attacks, achieving precise strikes.
