The use of EW in urban conditions has fundamental differences from operation in open terrain. Dense development, the heterogeneous materials of constructions, and a large number of extraneous signal sources change the behavior of radio waves and complicate predicting the effect of impact.
In the city, electronic warfare assets work in an environment where each building can both amplify and weaken the signal. This affects the action zone, the stability of interference, and the risk of side effects on one’s own and civilian communication systems.
The Propagation of Radio Waves in Urban Development and Its Impact on the Operation of EW
In dense urban development, radio waves propagate unevenly and unpredictably. Concrete constructions, metal elements, glass facades, and engineering communications affect the signal differently, changing its direction and level of attenuation.
Unlike open terrain, in the city the zone of EW impact rarely has clear boundaries. The signal can penetrate into internal courtyards or basements, or, on the contrary, weaken significantly within a few dozen meters. This complicates the precise configuration of systems and requires constant monitoring of the airwaves.
As a result, the effectiveness of EW in the city largely depends not only on technical parameters but also on an understanding of the features of the specific urban environment.
The Reflection of Signals in the City and the Formation of EW Dead Zones
One of the key features of the urban environment is the reflection of radio signals from buildings. Such reflections lead to the superposition of waves and the creation of areas with a reduced or unstable signal level, which are usually called «dead zones».
For EW, this means an uneven interference effect. Within a single block, areas with excessive impact and zones where the system practically does not work can exist simultaneously. This complicates the cover of positions and creates potential «windows» for the enemy’s operation.
That is precisely why, when planning operation in the city, it is important to take into account not only the action radius of the system but also the nature of the development and possible zones of signal weakening.
The Impact of EW on Civilian Communication Networks in Urban Conditions
The urban environment is saturated with civilian communication networks, including mobile communication, Wi-Fi, and other wireless systems. The operation of EW in such conditions increases the risk of unintentional impact not only on one’s own control channels but also on extraneous infrastructure.
Incorrect configuration or excessive interference power can lead to the disruption of civilian networks, complicate the coordination of units, and create additional operational risks. It is precisely these situations that are examined in detail in the article: «Electronic friendly fire: how to avoid the negative impact of EW on one’s own military units», which explains why controlling radiation parameters is critically important.
In urban conditions, EW must be applied as selectively as possible, taking into account the density of civilian networks and one’s own communication channels.
Positioning EW Antennas in Urban Development
The placement of antennas in the city is one of the determining factors of EW effectiveness. The height of installation, orientation, and mutual placement of antennas can substantially change the nature of the impact on the radio situation.
Unsuccessful positioning leads to the overlapping of one’s own zones or the formation of new dead areas. In urban conditions, it is often more effective to use several radiation points instead of a single source in order to compensate for the complex geometry of signals.
Thus, the correct positioning of antennas makes it possible to partially offset the limitations imposed by urban development.
Combining Mobile and Stationary EW Systems in the City
In urban conditions, the combination of mobile and stationary EW systems is often applied. Stationary solutions ensure the long-term cover of defined areas, while mobile systems make it possible to quickly react to changes in the situation.
In this context, antenna-feeder solutions play an important role, in particular the dome antenna complex Quadrifilar “4 in 1”. It is a set of antennas intended for forming a circular radiation pattern, which makes it possible to uniformly cover the space around a position.
Such a complex is not a standalone EW system but is used as a component of an overall solution together with transmitters, power, and control systems. Its application simplifies deployment in the city and reduces the dependence of effectiveness on the precise orientation of the antenna.
Combining different types of systems and antennas makes it possible to adapt EW to the complex urban structure.
The Practice of Using EW in Urban Combat Conditions
The practice of using EW in cities shows that successful operation is based on adaptation to the specific development. In different areas of the same city, conditions can differ substantially, which requires a flexible approach.
Solutions that combine a preliminary analysis of the radio situation, the correct placement of antennas, and control of the interference level are usually effective. Such an approach makes it possible to reduce dead zones and lower the side impact on one’s own and civilian systems.
The urban environment requires from EW operators not template solutions but the constant adjustment of actions depending on the situation.
Conclusions
EW in urban conditions is characterized by a number of technical limitations connected with dense development, the reflection of signals, and the presence of civilian networks. Effectiveness in such an environment depends on an understanding of the behavior of radio waves, the correct positioning of antennas, and the combination of different types of systems.
