1. The increasing use of UAS in various domains, including military and civilian applications, has raised concerns about their potential misuse. UAS can be employed for malicious purposes such as surveillance, reconnaissance, and even attacks. To counter this threat, a helicopter-mounted counter-UAS system or jammer is required to effectively neutralize and disrupt UAS operations. 2. Objectives: 2.1. Neutralize UAS Threats 2.2. Disrupt UAS Communication 2.3. Jam UAS Signals 2.4. Provide Real-Time Intelligence 3. Requirements: 3.1. Range and Accuracy: The system should have a range of at least 10 km and an accuracy of ± 10 meters. 3.2. Frequency Agility: The system should be able to operate on multiple frequency bands, including L, S, C, X, and Ku bands. 3.3. Power and Cooling: The system should be able to operate for extended periods ensuring reliable performance. 3.4. Weight and Size: The system should be lightweight & compact, allowing for easy integration onto a helicopter. 3.5. User Interface: The system should have a user-friendly interface, enabling easy operation and monitoring. 3.6. Redundancy and Fault Tolerance: The system should have redundant components and fault-tolerant design to ensure continued operation in case of component failure. 3.7. EMI/EMC: System should cater for EMI/EMC from on-board systems. The jammer should be omni-directional. 3.8. Weight Penalty: System should be of maximum 200 kgs for it to be fitted onto ALH Mk III class of helicopter. 3.9. Power requirements: The system should be able to operate on 400 Hz/ 115 V AC and max current which is available from ALH MKIII emergency bus bar. 3.10. Hard Kill/ Soft kill options: The soft kill option may comprise of jammers. However, in case of hard-kill options like DEW, the system should be integrated in a manner so as not to damage the aircraft itself i.e., safety angles etc. are to be catered for even at the cost of having limited area coverage.
