Electronic warfare (EW) testing: performance evaluation and success criteria
Introduction
Electronic warfare (EW) is an important element of modern military operations, especially in the context of countering unmanned aerial vehicles (drones). The main objective of REB systems becomes to neutralize the threat posed by guided projectiles such as drones by diverting them from their predetermined course or disabling them. However, it is not easy to assess the effectiveness of an EWS system, as success criteria can vary depending on many factors, including the conditions of use, the characteristics of the drone, and the characteristics of the EWS itself.
Challenges in assessing the effectiveness of an EWS
One of the main problems in evaluating REB performance is the use of hit/no hit criteria. This approach is not sufficiently accurate, because a downed drone does not always mean that the EWS is successful. Physical laws dictate that any object in the air will fall sooner or later, regardless of the REB intervention. Therefore, it is incorrect to assess success solely by the criterion of falling.
Importance of the statistical approach
In order to objectively assess the performance of the ERO, many parameters related to the characteristics of the defeat elements installed on the drone should be taken into account. For example, it is important to know the kill radii of different types of munitions:
- BOG: kill radius of approximately 10 meters.
- 82 mm mine: the kill radius is about 30 meters and the fragmentation reaches 150 meters.
These figures are indicative and depend on the specific operating conditions, but they give an idea of the minimum requirements that must be met to ensure safety.
Defining criteria for assessing the performance of an REB system
To adequately assess REB performance, it is proposed to use a comprehensive approach consisting of several testing stages. Each phase provides information for both EWR designers and drone operators, helping to better understand the countermeasures capabilities of EWR systems.
Stage 1 - Evaluation
This phase utilizes standard hardware without additional signal amplification modules or directional antennas. The test is conducted at 915 MHz with a transmitter power of 2-2.5 watts. Video is not taken into account, as it does not affect the REB operation.
Before starting the tests, it is necessary to make sure that the drone is able to fly the required distance without the influence of the REB. Main stage parameters:
1. Operator - REB" range: about 3 km. Testing at shorter distances is not reasonable.
2. Target setting: 2x2 meter grid, next to which the REB is set at a distance of 3-7 meters. Metal objects near the grid are excluded.
3. Objective: to hit the net. Hits on the net are allowed.
- Hitting the net is considered a target hit.
- Failure to hit the net counts in favor of the REB.
4. Failsafe setting: it is recommended to set for altitude gain (2-3 seconds) with transition to ANGLE mode. Automatic leveling and altitude gain allow to unambiguously determine the impact of the REB on the drone. If the drone goes into Failsafe, it indicates a miss.
Thus, this method eliminates arguments about whether the REB system worked or not, and also eliminates the need to argue about hitting or not hitting the target.
Conclusion
The effectiveness of REB systems requires a comprehensive approach to evaluation. Using simplistic criteria such as drone drop does not provide a complete picture. It is important to consider the kill radii of different types of munitions mounted on the drone, as well as testing under controlled conditions using standardized protocols. An integrated approach will allow the development of more accurate and reliable methods for evaluating REB performance, ultimately improving the safety and effectiveness of these systems in real-world combat environments.
