Which element provides information that allows the ICC operators to determine range and lateral extent of a formation of aircraft with on-board ECM capabilities?

• A. Radar Returns
• B. ECM Wedges
• C. IFF Data
• D. ECM Antennas

Answer: (B)

When aircraft are equipped with on-board ECM, normal radar reflections can be distorted or suppressed, so you need a way to infer where the ECM-equipped group is and how wide it spans. ECM wedges are that way. They’re sectorized representations of the ECM environment that the ICC builds from observations of how ECM signals appear across range and angle. By analyzing these wedge-defined sectors, operators can estimate how far away the formation is (range) and how much it extends to the sides (lateral extent).

Radar returns from ECM-equipped targets can be unreliable, which is why relying on raw radar data isn’t sufficient. IFF data can help identify whether something is friend or foe, but it doesn’t provide the geometric picture of a formation’s size and position in space. ECM antennas are the hardware used to transmit or receive jamming, not a data source that yields the formation’s range and lateral spread. The wedges specifically provide the information the ICC uses to map the formation’s location and footprint.
