Drone Detection for Modern CUAS Missions

Powered by Next Generation System Platform (NGSP®) Technologies 

The Challenge: Hostile Drones in Protected Airspace 

Uncrewed Aerial Systems (UAS) have rapidly evolved from tactical curiosities into serious and persistent threats. On today’s battlefield, and increasingly around critical national infrastructure, small, agile, and hard-to-detect drones penetrate defended airspaces with intent ranging from reconnaissance to direct attack.

These intrusions challenge traditional airdefense sensors. Small drones fly low, slow, and with minimal radar signature. They exploit clutter, hide among civilian traffic, and appear unpredictably. Effective CounterUAS (CUAS) operations depend on one essential first step: reliable, early, and unambiguous detection. 

The solution 

ASR-M® Radar with Enhanced NGSP® Technologies

Intersoft Electronics provides a robust radar-based response to this growing challenge. 

Our ASR-M® (Modular Air Surveillance Radar), equipped with the patented technologies of the Next Generation System Platform (NGSP®), delivers high-performance drone detection in complex and contested environments.

Advanced Processing
Technologies

At the core of this capability are the advanced processing techniques described in Intersoft Electronics’ Advanced Processing Technologies whitepaper. These techniques enhance radar performance across key areas relevant to drone detection:


  • Adaptive clutter suppression to distinguish drones hidden in ground or urban clutter 

  • High-resolution doppler processing to detect low speed and hovering targets

  • Enhanced track initiation and continuity for small maneuvering drones

  • Integrated classification support to help differentiate drones from birds or benign air traffic 

  • Multisensor integration readiness, enabling a broader CUAS system architecture 

Key Advantages for CUAS Operations

  • Reliable Detection in Challenging Conditions.
    NGSP®’s signalprocessing engine boosts sensitivity and discrimination, allowing operators to detect small drones among clutter, buildings, or vegetation — conditions where legacy radars struggle.

  • High Accuracy Through Advanced Target Processing.
    Improved doppler and spectral analysis supports precise measurement of slow moving or hovering UAS, ensuring early warning and reducing false alarms.
  • Operational Flexibility 
    The NGSP® platform supports semifixed or integrated deployment models. This makes it suitable for temporary event protection and permanent infrastructure defense. ASR-M® systems for normal airport surveillance can be equipped with a dedicated channel for drone detection.

  • Efficient Handling of HighDensity Airspaces 
    NGSP®’s processing chain is designed to cope with the complexity of today’s lowaltitude air picture, maintaining performance even in dense or cluttered environments. 

  • Scalable and Open Architecture
    NGSP® technologies allow smooth integration with commandandcontrol systems, effectors, and multisensor CUAS frameworks — supporting both standalone radar use and layered defense architectures.
