Excerpt: This section covers most sensor types that are of military interest. Inertial, chemical, biological and nuclear sensors are covered in other sections. This section also covers the laser technologies that are not covered in other sections. The sensors included are acoustics for air, terrestrial and marine platforms; electro-optical; gravity meters and gradiometers; lasers; magnetometers and magnetic gradiometers; and radar. Obscurants are included as one method of countering some sensors. The acoustic sensors are used militarily for locating submarines, mines and lost objects; depth sounding; bottom mapping; and weapon activation and homing. They are used commercially for fish finding, seismic exploration at sea and for petroleum and mineral exploitation. Electro-optical sensors are typically used for night vision devices and for terminal guidance for smart weapons. Gravity meters measure gravity magnitude and gravity gradiometers measure gravity gradients. These sensors are used for missile siting, inflight guidance, and to aid in inertial navigation. They are used commercially in geophysical surveys. Military lasers having less than 15 kW output power are used primarily for limited visibility operations and to improve targeting accuracy with guided weapons. Magnetic sensors detect the presence of a magnetic field and measure its magnitude and/or direction and are used militarily for covert detection of submarines and mines and for proximity detection by ordnance fuses. They are used commercially in geophysical surveys. Radar is used militarily on all types of platforms and at fixed sites for detecting and locating targets, for weapon guidance and to obtain information about earth features and atmospheric conditions. Major commercial uses are air traffic control, ship tracking for collision avoidance and weather tracking. Gravity gradiometers, lasers and radar are used in the delivery of WMD. No major emerging technology developments are underway. A large part of sensors and lasers technology is enabling for military applications as they are the eyes and ears of many military systems and provide a great proportion of the data required for prosecution of military activity.
