Arzenal P-18H modernized radar at IDET 2015
 
 
New modernized radar P-18H early warning radar developed by Arzenal from Hungary.
The P-18H is modernized version of the P-18 or 1RL131 Terek (also referred to by the NATO reporting name "Spoon Rest D" in the west) a 2D VHF radar developed and operated by the former Soviet Union. The P-18H radar has newly developed hardware. The frequency range was extended and the operational frequency is increased from 4 to 41, allowing the immediate automatic frequency tuning.

The transmitter and reciever units consist of only solid state elements. The transmitter consists of modular systems, which greatly facilitates the correction of possible failiures.

In the new radar station, number of vehicles are reduced from 4 to 2: equipment vehicle, antenna vehicle. An aggregator is integrated in the equipment vehicle, which provides the radar’s smooth operation in case of power failiure using an uninterruptible power supply.

Due to its meter wavelenght range, the radar is able to detect aircrafts using stealth technology. The radar spare parts base is based on the latest commercial off-the-shelf items. Transmitter is solid state type based on pulse-compression principle. Test and diagnostic equipments are built in.

The modernization improves the surveillance probability, the path of air targets is automatically tracked. The station is able to recieve data from other radars, the informatioon exchange between radars is based on agreed exchange protocol. The radar requires low maintenance, in case of newly built-in units the mean time between failures level is high (approx. 12.000 operating hours).

The P-18H is a two-dimensional radar, which automatically defines the azimuth and range. The third parameter can be provided by a modern locator height-finder. The parametres of the transmitted signal and the parameters of the reflected, processed signal, the secondary signal display, which already takes into consideration the displacement and the speed of the target point, appears on ARM-0 and the remote ARM-1 workstation.

As an option recognition system can be used, in automatic or semi automatic mode, depending on the importance of the national origin of flying objects for the users. The current status of the airspace is documented automatically, in offline and online mode.The task of CDU is to establish the man-machine interface between the operator and the radar. This unit is responsible for the switch on/off of the radar, the operation mode selecting, control of several radar units and displays analogue air picture and synthetic radar information on a single interface, furthermore, provides objective control functions. The personal computer-based equipment is user-friendly and perspicuous, the whole radar picture can be seen on the display interface and the operator can get a broad picture of operation of the radar.
