The AN/MPQ-64 Sentinel is a three-dimensional radar used to alert and queue Short Range Air Defense (SHORAD) weapons to the locations of hostile targets approaching their front line forces. The Sentinel radar is deployed with forward area air defense units of the U.S. Army and USMC. The radar uses an X-band range-gated, pulse-doppler system. The antenna uses phase-frequency electronic scanning technology, forming sharp 3D pencil beams covering large surveillance and track volume. The radar automatically acquires, tracks, classifies, identifies and reports targets, including cruise missiles, unmanned aerial vehicles, rotary and fixed-wing aircraft. It uses a high scan rate (30 RPM) and operates at a range of 40 km. The radar is designed with high resistance to electronic countermeasures (ECM). Mounted on a towed platform, it can be positioned remotely from the rest of the unit, operated autonomously and communicate with the Fire Distribution Center (FDC) via wideband fiber-optic link. It can also distribute its data over a SINCGARS radio network. ==Main characteristics== * Acquisition and Tracking Surveillance Radar * Proven X-band, 5D Radar * 30 RPM (ABT) 20 RPM (ADEF) Rotation Rate * Low-altitude, medium-range air defense sensor * Detects fixed- and rotary-wing aircraft, cruise missiles, and UAVs at reduced ranges and trucks on a highway * Azimuth: 360 deg; altitude: 4000 m; range: 8000 m effective * Large Surveillance and Track Volume * Automatic Programmable Digital Output * COTS Signal and Data Processor * Low Side Lobes and Narrow Pencil Beam * Electronic Countermeasures (ECM) and Anti-Radiation Missile (ARM) resistant * High mobility, transportability, and reliability * Deployed using modified HMMWV fitted with a 400 Hz on-board generator * Provides identification of friendly aircraft through IFF 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「AN/MPQ-64 Sentinel」の詳細全文を読む スポンサード リンク
