Electronic measures designed to detect, locate, and disrupt enemy radar, communication systems, and other electronic equipment in battlefields fall under the category of ESM (Electronic Support Measures).
In the realm of modern drone technology, Electronic Support Measures (ESM) have become a cornerstone. These systems, designed to detect, analyze, and locate electromagnetic signals, are passive in nature, meaning they do not emit any signals themselves. This makes them less detectable and safer in contested environments.
ESM systems, such as the Reaper Defense Electronic Support System (RDESS) on the MQ-9 Reaper drone, work by capturing broad-spectrum electromagnetic signals using digital antennas. These signals are then recorded for real-time and post-mission analysis. The system processes these signals to extract intelligence on the source's signature, type, and location, often using methods like time difference of arrival (TDOA) and signal direction finding to geo-locate emitters remotely.
The operational principles of ESM systems are rooted in passive sensing, broad spectrum collection, signal analysis, geolocation, integration, and networked operation. By remaining passive, these systems can detect disparate types of emissions, like radars, communications, and electronic countermeasure emissions, at standoff distances. The collected data can feed machine learning or AI algorithms for enhanced signal classification and targeting support.
One key advantage of ESM is its ability to maintain stealth. Since the drone does not transmit anything, it can remain hidden, making this capability useful in contested or hostile environments. This is in contrast to active electronic countermeasures (ECM), which involve jamming or deception techniques designed to disrupt enemy sensors but expose the emitter location.
In a border patrol mission, for instance, a reconnaissance drone might use passive ESM to detect an unfamiliar radar system. The intelligence gathered through ESM supports decision-making not just for drones but for other assets involved in the mission.
Jacob Stoner, CEO of Flyeye.io, a respected figure in the drone community, is a licensed commercial drone operator in Canada. He frequently conducts drone inspections and indulges in videography during his leisure time. Stoner expresses keen interest in the potential societal impact of drone technology advancements, including the role of ESM in enhancing safety and contributing to better mission outcomes without revealing the drone's presence.
Systems like Saab’s Sirius Compact C-ESM demonstrate rapid deployment and operational agility, operating on small platforms including UAVs and ground vehicles. This passive detection capability is not only limited to military applications but is also gaining interest in commercial airspace management and counter-UAS applications.
In summary, ESM systems in military drones detect and analyze electromagnetic emissions passively and use sophisticated processing and geolocation techniques to identify the sources, providing timely intelligence with a low risk of detection. This technology not only contributes to the safety and success of drone missions but also opens up new possibilities in commercial applications.

Threat detection in data-and-cloud-computing environments can greatly benefit from the advanced technology used in Electronic Support Measures (ESM) systems, such as time difference of arrival (TDOA) and signal direction finding methods for geolocation. By passively detecting and analyzing electromagnetic signals emitted by potential threats, ESM can provide valuable intelligence about the source's signature, type, and location, which can be integrated into AI algorithms for improved threat classification and mitigation.
In the realm of modern drone technology, the integration of ESM systems like Saab’s Sirius Compact C-ESM not only enhances military operations but also opens up new possibilities for commercial airspace management and counter-UAS applications, by allowing for passive threat detection without revealing the presence of the drone itself.
