352 SOW C-sUAS Salient Characteristics

Item: Passive Acoustic C-sUAS Sensor System

P/N and/or Description: Discovair array G2+ or Equal

Manufacturer: Squarehead Technology or Equal

In order to be considered technically acceptable as "equal" to the brand name specified, a product must meet the following essential (salient) characteristics:

1. Detection Method: The system must be a passive acoustic sensor that detects, classifies, and tracks unmanned aircraft systems (UAS) based on their sound signature. The system must not emit any radio frequency (RF) signals as part of its detection process.

2. Target Classification: The system must be capable of detecting and classifying both Group 1 and Group 2 UAS.

3. Environmental Durability: The individual sensor unit must have an Ingress Protection (IP) rating of IP65 or higher, ensuring it is dust-tight and protected from water jets.

4. Operational Resilience: The system is expected to operate effectively in environments where both friendly and adversary RF activity may be present. This includes GNSS denial/degradation, RF jamming, electromagnetic interference, and congested spectrum conditions commonly associated with Counter-sUAS operations. The desired solution should maintain detection and tracking capabilities despite these conditions.

5. Detection Range: The system must be capable of detecting a Group 1 UAS (e.g., DJI Mavic or similar) at a minimum range of 500 meters under optimal, low-noise environmental conditions.

6. Sensor Field of View: Each individual sensor unit must provide a minimum detection field of view of 100 degrees in azimuth and 100 degrees in elevation.

7. System Scalability: The requirement for networking four sensors are intended to establish a minimum operational baseline to support distributed site coverage and improved target localization. Solutions capable of supporting additional sensors are desirable. Systems supporting fewer than four sensors would likely not satisfy the operational requirement.

8. Target Data Output: The ability to provide target location information, including azimuth and elevation, over a standard IP network is preferred to facilitate integration with existing and future command-and-control systems. Proprietary formats may be acceptable provided they can be readily integrated into common operating picture platforms and do not require extensive custom development.

9. Portability: The system must be man-portable. The weight of a single, ruggedized sensor unit shall not exceed 10 kg (22 lbs). The weight threshold of 10 kg or less per sensor is intended to support rapid deployment and employment by a single operator in both fixed-site and expeditionary environments. Slightly heavier systems may be considered if they remain man-portable and do not significantly impact operational mobility.

10. Compliance: The product must be Trade Agreements Act (TAA) compliant.
