    Radar rangefinder AN/MPQ-51 is a pulsed radar operating in the frequency range 17,5-25 GHz, which allows measurement of the target range and providing this information to the radar illumination conditions suppress the last active interference.

    item information processing Designed for automatic data processing and connecting battery complex. The equipment is located inside the cab mounted on a single axle trailer. It consists of a digital device automatic processing of data from radar target designation of both types, equipment identification system "friend or foe" (antenna mounted on the roof), interfaces and communications.

    control station neredovogo platoon firing AN/MSW-11 is used as the control center and fire command center platoon. Fasting is also able to solve the problems of information processing points, which it is similar in composition of the equipment, but additionally equipped with a control panel with indicator Omnidirection other means display and controls. Post includes a crew commander (fire control officer), radar operator and operator communications. On ocnove information purposes derived from the radar and target designation AN/MPQ-48 is displayed on the circular review, an assessment of the air situation and appointed shelled goal. Target designation data on it and the necessary commands are transmitted to the radar illumination AN/MPQ-46 best platoon firing.

    tests and operation

    Combat complex work and functioning of its assets in the process of shooting carried out as follows.
    Pulse radar and targeting AN/MPQ-50 station targeting AN/MPQ-48, operating in continuous wave mode, search for and detect air targets. At the command post AN/TSW-8 battery when it is operating in conjunction with item processing (as in the forward firing platoon - in the control AN / MSW-11) on the basis of obtained data from these radar target identification problems are solved, evaluation of air situation, determine the most dangerous targets, target designation fire section. After the capture of target illumination station AN/MPQ-46 carried her support automatic or (usually in difficult noise conditions) in manual mode. In the latter case, the operator uses a battery command post range information obtained from radar rangefinder AN/MPQ-51. In the process of target tracking station backlight produces its exposure. With a rocket launcher selected for shelling targets induced in the pre-emption point. Homing SAM captures the goal.

    After coming

    start command (with battery or manual control point forward platoon firing) missile leaves the rail, and reaching a certain speed, begin to work on the target. While its seeker uses the reflected from the target and received from the station lighting (reference) signals. Evaluation results of shooting is performed based on data obtained by processing the Doppler signal at the target station backlight data processing station.

    Modernization

    Modernization Program SAM "Improved Hawk", which began in 1979, has now entered the third phase. At this stage the planned work on several fronts, the main ones are:

    - giving the complex the simultaneous destruction of several goals through the use of radar illumination additional antenna with a wide beam. It is believed that when firing at several targets range of their defeat will be 50-70 percent. range achieved when firing at a single target.

    - Replacement manual battery and item information processing control station, basically similar post best platoon firing, but differ by the presence of a second controller and digital computing device. Both the remote control provides fast access with digital display means air situation display similar means SAM "Patriot".

    - Increased mobility SAM while reducing the amount of the complex transport units (from 14 to 7) by allowing the transport of SAM on the launcher and replace the transport and loading vehicle M-501E3 machine equipped with hydraulic lift, which was established on the basis of truck. On the new TPM and its trailer will be transported by a single rack with three-Zour on each. It is reported that during deployment and retrieval battery with halved.

    - radar equipment and PU complex navigation equipment and digital computing device to give a set of possible goals to fire on the data from radar AN/MPQ-53 SAM "Patriot".

    Upon completion of the modernization program SAM "Improved Hawk" in the United States and other NATO countries plan to create modifications of this complex, which would largely meet the requirements of modern anti-air attack weapons.

    Thus, the American firm "Raytheon" develops radar ACWAR [Agile Continuous-Wave Acquisition Radar), which can be replaced by radar targeting both types. This three-coordinate station will have an antenna with electronic beam scanning in elevation and mechanical - in azimuth. Mention is also made of the possibility (in case of a new modification of missiles) use radar for guidance ACWAR Zour on average-trajectory, while excluding from the SAM station target illumination.

    The structure of a new modification of the complex "Improved Hawk", intended for the Norwegian Armed Forces, included three-coordinate radar LASR (Low Altitude Survellance Radar), developed by the American company "Hughes" on the basis of radar serifs artillery positions AN/TPQ-36 .
