Cosite Analysis
Designing and Upgrading Command and Control Communications Systems for First-Time Success


Pole/Zero®’s Cosite Interference Analysis models the following cosite interference mechanisms:

Transmit Mode

- Broadband noise and spurious output
- Reverse intermodulation distortion

Receive Mode
- Receiver desensitization
- Reciprocal mixing
- Cross modulation
Receive intermodulation

With antenna to antenna coupling  data  derived either from a Delcross Technologies simulation or via empirical  techniques, the Pole/Zero cosite analysis proceeds as follows:



​Military Command & Control (C2) platforms employ several RF communications channels to ensure force coordination over long distances. Unbeknownst to the warfighter, often these critical communication distances are not realized due to self-generated or cosite interference. This degradation has, at its source, insufficient antenna isolation on the C2 platform, lack of transmitter spectral purity and receiver vulnerability to desensitization from local interference. Therefore, antenna placement, transceiver selection and cosite interference mitigation techniques are central to ensuring full communications range is realized.

To meet these challenges, Pole/Zero Corporation and Delcross Technologies have partnered to offer our system integration customers a “turnkey” source for solutions to the challenges of antenna placement optimization and RF cosite interference mitigation in shipboard, airborne and vehicular applications.




Delcross Technologies is a recognized industry leader in simulating installed antenna performance and antenna-to-antenna coupling characteristics on complex military platforms. In conjunction with Pole/Zero’s state of the art RF cosite interference analysis software and mitigation equipment, the Pole/Zero and Delcross Technologies team will afford developers of new or upgraded radio communications platforms, first-time success in fielding these systems.
