The AN/SPS-67(V) provides C-Band radar navigation, station keeping/surface search functions, and a digital moving-target indicator
The new radar has at least three air-to-air modes (multi-target track, track while scan and dogfight), plus at least six air-to-ground modes (synthetic aperture, ground moving-target indicator
, ground moving-target track, spotlight Sar and high-resolution ground mapping), as well as EW functions.
It uses a passive phased-array antenna, a transmitter based on air-cooled traveling-wave tubes (TWTs), and a receiver with a fully coherent, pulse-Doppler moving-target indicator
(MTI) with an adaptive wind-compensation function.
Radar function will include swath SAR and moving-target indicator
modes for wide area detection of fixed and moving targets with a spotlight SAR mode for high resolution surveillance of fixed targets.
Features of the radar include a wide-area moving-target indicator
(MTI) mode that can detect moving targets in a 6,200- square-mile area in a wedge ranging from 18 to 75 km, a combined SAR/MTI strip mode with 20-foot resolution over a swath 23 miles wide at ranges of 12 to 68 mi, a SAR spot mode with 6-foot resolution covering six square miles, and a sea-surveillance mode.
TIPS is proposing a high-power, multi-mode two-dimensional electronically scanned array that would perform simultaneous synthetic aperture radar and moving-target indicator
The payload of the ERMP is expected to include a syntheticaperture radar and moving-target indicator
, with Northrop Grumman (Baltimore, MD) and General Atomics (San Diego, CA) among the companies likely to compete to provide it.
The operative sensor is the Thales (Paris, France) Target radar, which is a J-band multimode radar, with its primary mode being a moving-target indicator
In March, a French Army Horizon airborne-early-warning (AEW) helicopter participated in the NATO's Strong Resolve exercise in Norway, during which the helicopter's moving-target indicator
(MTI) detected an incoming "enemy" amphibious attack prior to landing, thus providing enough time to prepare defenses to repel them.
The moving-target indicator
(MTI) is a type of radar designed to detect moving targets on the ground.
Signals-intelligence (SIGINT) systems, a moving-target indicator
and foliage-penetrating radar are among the equipment under consideration for fit aboard the Global Hawk.
The ACS will merge in one system the capabilities of Guardrail and the Airborne Reconnaissance Low (ARL) system, combining the Guardrail's communications- and electronics-intelligence with the capabilities currently provided by the ARL system: a synthetic-aperture radar, a moving-target indicator
, and electro-optical/infrared sensors (see "NEW ISR System to Replace Guardrail, ARL," JED, September 1999, p.
