Radar and Radio Systems Coverage Optimization

Using simulation to predict, analyze, optimize, and plan the coverage given by radio and radar systems is key to reduce development and planning times together with costs. Also, in some cases, this is the only feasible approach to identify and fix communication issues. This webinar overviews simulation strategies for propagation analysis in complex environments, including among others large-scale terrain, cities, or buildings with interior detail. Additionally, the effects of interference and jamming will be covered and how the frequency allocation for a system with many transmitters can be optimized automatically.


Large Platform Co-site Interference Mitigation

Platforms like frigates, fighter aircraft and armored vehicles tend to contain many transmitting and receiving antennas for a variety of electronic systems such as communication systems (including SATCOM), radar, positioning systems, and more. Even though these systems may operate on different frequencies, due to their proximity they may interfere. To analyze for co-site interference using electromagnetics simulation solutions requires...

(a) accurate determination of the coupling between antennas over a broad frequency range, even if platforms are complicated, and no direct line of sight may exist,

(b) evaluation of the impact of non-linear electronic effects including harmonics, intermodulation, IF breakthrough, image frequency, Tx and Rx spectra, and receiver blocking.

Altair’s full system solution for analysis of co-site interference will be presented in this webinar, along with a practical example where an interference problem is identified and eliminated.


Electromagnetic Simulation for Electronic System Design in Aerospace and Defense

The aerospace and defense industry relies heavily upon advanced electronic systems for field communications, control, targeting, threat detection, asset tracking, health monitoring, and theater operations. These advanced electronic systems often require multiple, high-fidelity antennas. Those antennas, in turn, require interference free integration for maximum signal strength and reliability.

Collocation Interference Analysis Workflow And Exercise

RF co-site interference occurs when two or more co-located RF systems affect one another’s smooth operation. This normally occurs when two or more RF systems are operating physically close to one another and they are operating in such a way that one of the transmitters negatively impacts one or more receivers. This document explains you the workflow and includes an exercise following the steps to solve a co-site interference problem from the creation of the transmitters, receivers and antennas, through the stations and coupling loss matrices, and to the analysis.
