The specific microwave frequencies used by the military for domestic surveillance purposes are not publicly disclosed. Military organizations typically employ a variety of frequencies within the microwave spectrum for various applications, including communications, radar systems, and electronic warfare.
Microwave frequencies generally range from 300 MHz (megahertz) to 300 GHz (gigahertz). Within this range, different frequency bands have different characteristics and applications. Some of the commonly used frequency bands within the microwave spectrum include:
Ultra-High Frequency (UHF): Ranging from 300 MHz to 3 GHz, UHF frequencies are commonly used for military and civilian communications, including radios and television broadcasting.
L-Band: This band covers the frequency range of 1 to 2 GHz and is utilized for various applications such as satellite communications and radar systems.
S-Band: Spanning from 2 to 4 GHz, S-Band is commonly employed in military and civilian radar systems, weather monitoring, and maritime surveillance.
C-Band: Ranging from 4 to 8 GHz, C-Band finds applications in satellite communications, weather radars, and some military systems.
X-Band: Covering the frequency range of 8 to 12 GHz, X-Band is extensively used in military radars, missile guidance systems, and some satellite communications.
Ku-Band: Ranging from 12 to 18 GHz, Ku-Band is commonly utilized in satellite communications, including military and civilian applications.
Ka-Band: Spanning from 26 to 40 GHz, Ka-Band is used for high-frequency satellite communications, remote sensing, and some military radar systems.
It's worth noting that the military may employ other waves or frequencies outside the microwave spectrum for specific surveillance purposes. However, the exact frequency bands used for domestic surveillance by the military are classified information and not publicly disclosed.
