Frequency Difference of Arrival based Direction of Arrival for Radar Signals

Source

Source summary

Develop compact hardware and FPGA-deployable firmware that estimate radar-signal direction of arrival from frequency differences, for integration with ELINT/ESM systems across platforms. The source specifies 2–18 GHz coverage, 360-degree azimuth, sub-one-degree RMS accuracy, support for pulses above 50 nanoseconds, fast computation and tolerance of real-system noise.

Secure Boot and Encrypted Storage with RISC-V Core

Develop RISC-V-based secure boot and encrypted storage for connected devices, including IoT and automotive systems. The ask covers checking firmware before execution and protecting stored firmware and video data against unauthorised access or modification. It describes hardware-enforced protection as an objective rather than a security guarantee.

Mitigating risks of unauthorized USB devices: a custom PC solution

The Indian Air Force reports repeated use of unauthorised USB devices on both AFNET and civil-internet computers despite software controls. It proposes customised PCs and approved peripherals whose USB interfaces are physically converted to specified adapter types, adding a physical barrier intended to reduce accidental or malicious insertion.

Linux desktop in Windows environment

Mazagon Dock has Windows-based security controls but has been advised to use Linux desktops on internet-facing defence machines. The challenge asks for a hardware or software mechanism that gives Linux desktops equivalent central control, including directory authentication, antivirus, network access control, group policy, certificate-token use, approved removable media, printing and encryption.
