With the development of drone technology, the requirements for counter-drone systems are becoming increasingly stringent. Previously referred to as "low, slow, and small," drones are now also characterized by "low, fast, and small," particularly with the application of racing drones. Statistics show that drones can cause 80% to 90% of the equipment damage in warfare. Therefore, from the perspective of offensive and defensive operations, counter-drone systems face higher requirements. For instance, it is necessary to establish an aerial defense system capable of real-time classification and batch interception. This can be achieved through detection methods such as radar, electro-optics, and acoustics, combined with soft and hard kill methods like high-powered lasers and high-energy microwaves. Additionally, source-targeted attacks, such as using low-cost missiles to strike the drone' launch point, can minimize large-scale damage later.

Reflecting on the state of the Russia-Ukraine conflict, we have explored new research directions for counter-drone equipment. We concluded that, first, it is essential to construct a multi-system collaborative sensor network. Second, interception equipment must be layered and categorized for deployment. Third, cost-effective interception equipment needs to be developed. Finally, low-cost anti-aircraft missiles can also be considered.

In the early stages, the primary counter-drone approach relied on VCO (Voltage-Controlled Oscillators), which required high power. However, as drone technology has advanced, especially with improvements in frequency hopping, spread spectrum technology, and communication protocol restructuring, the reliability of drone communication links has significantly increased, posing higher demands on counter-drone technologies. Thus, the era of purely high-power solutions is over, and we have now entered an era dominated by software-defined radio and algorithm-based solutions. The focus of future development will be on leveraging algorithms and low-power interference methods.

Today' discussion focuses on the low-altitude economy, with safety being a critical module. Within the safety framework, it is essential to address the impact of rogue (unauthorized) drones on regular flight routes. Solving the distinction between authorized (properly registered) drones and rogue drones is crucial, and precision targeting is the key. The core technology for precise targeting remains SDR (Software Defined Radio) based. To distinguish between rogue drones and those on the whitelist, we primarily employ SDR-based counter-drone technologies.

This year, we have taken the lead in launching digital module-based countermeasure systems specifically targeting racing drones, capable of effectively disrupting all FPV and ELRS series drones domestically. The primary characteristics of this module include the ability to generate dedicated FPV jamming codes with extremely low power requirements, achievable at levels below 10 watts. This allows the equipment to be lighter and more compact, with longer operational durations. Moreover, algorithmic advancements effectively address the countermeasures for frequency-hopping and spread-spectrum drones. Key features include dedicated SDR jamming codes, modular design for rapid deployment of anti-racing-drone capabilities, and algorithmic upgradeability to ensure equipment remains effective and combat-ready.

Based on the SDR-driven countermeasure algorithms for racing drones, we have introduced three solutions aimed at addressing defense challenges along railway routes:

1. EWALL Technology: The innovative application of EWALL is highly effective against racing drone swarm attacks, forming an invisible electronic wall that prevents drones from breaching protected areas. Importantly, it operates without disturbing the local population or affecting the daily lives of nearby residents. For example, we implemented this technology at a customs site to combat drug smuggling. Along a 5-kilometer stretch of coastline, we established an electronic wall to prevent drone smuggling activities, operating 24/7 without interruption. EWALL equipment can be deployed on land, ships, and vehicles to achieve regional protection.

2. Vehicle-Mounted Array System: To address the significant damage to equipment on modern battlefields, we have designed a vehicle-mounted quad-array counter-drone system. This system can be installed on vehicles to meet the anti-drone requirements for both individual vehicles and convoys, acting as a mobile steel fortress. It provides robust protection for critical equipment vehicles, preventing suicide attacks from drones and racing drones. These solutions aim to deliver comprehensive protection against emerging threats from drones, ensuring safety in diverse scenarios and critical environments.

3. The third scenario involves integration with troop protection for individual soldiers, aiming to prevent suicide attacks by racing drones against soldiers. We have introduced a personal anti-racing drone kit, which includes drone detection and handheld countermeasure equipment. This kit enables rapid counteraction against racing drones, preventing them from causing harm to personnel.

These solutions are specifically designed to address the threats posed by racing drones in various scenarios, achieving the protection of fixed key locations, critical equipment vehicles, as well as the lives of soldiers and special police forces. This ensures enhanced safety for personnel and critical assets in high-risk environments.
