SBIR-STTR Award

An update of MIL-STD-464 and MIL-HDBK-235 has lowered the Peak E-field and raised the average E-field requirements for susceptibility testing of aircraft. The equipment presently used for testing was not designed to cover both peak and average power to this extent. While it might be possible to achieve coverage by adding multiple devices, it would be more convenient and economical to achieve coverage with a single device at each frequency range. H6 Systems proposes to develop a multi-tube transmitter that is optimized for susceptibility testing and meets power requirements in a particular frequency range. Such a system would be desirable for use at government test centers such as Dahlgren, Redstone, Patuxent River and White Sands.

Benefit:
A working design for a multi-tube Crossed Field Amplifier transmitter will extend testing coverage of the MIL-STD-464 and MIL-HDBK-235 requirements.

H6 Systems proposes building a transmitter based on a modified coupled cavity TWT from CPI to increase coverage of MIL-STD-464C. Present testing methods are lacking in the coverage of power for frequencies from 3.0 3.3 GHz. The new transmitter will allow testing at both peak and average powers and will fill requirements for fields shipboard not in the main beam.

Benefit:
The more comprehensive susceptibility testing provided by this transmitter will ensure proper functioning of aircraft and ordinance in the field.
