Radar cross section reduction of broadband structure integrated antenna apertures (version 2)

Reference number
Coordinator SAAB Aktiebolag - Saab Aerosystems
Funding from Vinnova SEK 3 087 500
Project duration October 2010 - October 2013
Status Completed

Purpose and goal

The theoretical study has shown the possibilities and limitations of combining different techniques for signature reduction. Significant functionality has been implemented and validated in the calculation tool, which has allowed extensive verification of the theoretical concept proposals. Extremely low signature levels have been obtained except for low frequencies and for some angular sectors. These specific issues should be studied further in order to achieve even better results.

Results and expected effects

The theoretical results and the improved calculation tool is directly transferable to real projects that require low signature or to use in projects with international cooperation. This increases industry expertise both in the development and integration of sensors with extremely low passive signature. Swedish aerospace industry´s ability to compete is thus expected to strengthen and contribute to an improved international position. An even already good cooperation between industry and university has been strengthened.

Approach and implementation

The project has been a close collaboration between industry and academia with Saab as a requirement specifier and project manager. Lund University has contributed theoretical studies and calculations. Efield expanded the functionality of the calculation tool, so that the LO-techniques can be analyzed by Saab. By this, each party contributed with unique expertise. The work was conducted with quarterly follow-up meetings where all parties discussed their obtained results and direction for the next period. In between, ideas and results have been exchanged between the participants.
