You can measure the performance of the antenna by using a handheld spectrum analyzer to configure the antenna pattern. The sweep time needs to be set long enough to synchronize to the rotation of the golden antenna.
Thus, the general requirements for an airborne SIGINT antenna are a miniaturized volume, planar configuration, relatively wide frequency range, appropriate antenna pattern, and suitable physical shape for aviation operation.
Through the analysis of the antenna pattern, it can be concluded that its shape is similar to a sinc function.
The dual-optimized antenna enables installation technicians to change the antenna pattern with the flip of a switch to maximize the performance of the access point in single or multiple floor deployments.
The input type of each variable parameter (as horizontal and vertical antenna pattern, e.i.r.p., propagation environment etc.) is modelled like statistical distribution function.
In AC systems, link margin can be increased (or the overall power consumption can be decreased) with a careful design of antenna pattern. A directivity can be placed by electronic beamforming and/or mechanical beam steering according to positions and Euler angles of the aeronautical platforms.
Antenna radiation pattern, or briefly antenna pattern, is defined as a mathematical function or graphical representation of antenna radiation pattern of spatial coordinates.
