Challenges DRISHTI
Indigenous Multi-Node Electronic Deception System
The challenge is to develop an Indigenous Multi-Node Electronic Deception System capable of performing coordinated radar deception using a network of synchronized deception nodes.
The system aims to introduce a new electronic warfare capability based on distributed deception, where multiple deception nodes operate together to generate believable radar signatures and synthetic radar targets.
The proposed system will consist of:
• Multiple Deception Nodes (DN) deployed around protected radar systems
• Each node equipped with Digital Radio Frequency Memory (DRFM) capable of capturing radar signals and retransmitting modified signals
• A central Deception Controller responsible for coordination and deception planning
• High-precision GPS-based synchronization to maintain coherent timing between nodes
• AI-assisted algorithms to adapt deception strategies in real time.
Defensive Mode – Radar Position Masking
In this mode, the system protects friendly radar assets from anti-radiation missile attacks.
When a radar emits, deception nodes capture the radar signal and retransmit it from different locations with controlled delays. This creates multiple apparent radar emission sources in the electromagnetic spectrum.
Enemy ESM systems detecting these signals will perceive several radar emitters rather than the actual radar location. As a result, adversary targeting systems cannot reliably determine which emitter corresponds to the real radar.
This deception increases the survivability of radar installations by forcing adversaries to either attack multiple false positions or risk wasting missiles on decoys.
Offensive Mode – Ghost Target Generation
In offensive electronic warfare operations, the system can generate synthetic radar targets on enemy radar systems.
Deception nodes intercept radar pulses transmitted by adversary radar systems. Using DRFM processing, the captured radar signals are modified and retransmitted with controlled delay, Doppler shift, and signal characteristics to simulate reflections from aircraft or missile targets.
By coordinating multiple nodes, the system can create realistic radar target formations that appear as approaching aircraft or missile groups.
These ghost targets can:
• overload enemy radar tracking systems
• force adversaries to deploy interceptors against non-existent threats
• reveal enemy air defence positions when they respond to false targets
• create operational diversion during strike missions.
