What is one major limitation of Firefinder Radar systems?

The correct choice highlights one of the significant vulnerabilities inherent in Firefinder Radar systems: their susceptibility to electronic warfare and jamming. This limitation is critical because it affects the system's operational effectiveness.

Firefinder Radars, which are intended to detect incoming artillery rounds by analyzing their trajectory, rely on electronic signals for both sending and receiving data. In a modern battlefield scenario, adversaries can deploy electronic warfare tactics to disrupt these signals, rendering the radar ineffective. This can include broadcasting a powerful jamming signal that overwhelms the radar's ability to interpret incoming data or even using counter-radar techniques to mislead the system.

The operational environments where Firefinders are utilized also present challenges. Unlike some other systems, Firefinder Radars do not necessarily face limitations such as the need for constant manual operation, high deployment costs, or visibility issues due to weather. The design of these radars supports automated functions to mitigate operator workload, the costs are justified by their capabilities, and they are engineered to operate under various weather conditions, albeit with potential performance dips. Thus, the concern over electronic warfare and jamming stands out prominently as a major limitation.
