Description

The modern digital signal processing system is based on powerful DSP circuits and performs most of its functions in a programmed manner, enabling to implement advanced processing algorithms and flexibly adapt it for particular needs. A special processing channel has been implemented for detecting sea surface targets against sea clutter and multiple algorithms have been employed to detect hovering helicopters. The radar uses well proven hardware, based on industrial computer boards and sophisticated algorithms, for the automatic tracking of manoeuvring air targets.

Targets are detected automatically, their tracks initiated then interrogated whether friendly or hostile, and the proper labels are attached to the tracks. Radar data are automatically transmitted by radio to remote users operating within the radio communication range. Additionally, data recording capability is provided, enabling to register the detected plots and tracks over a period of several hours of radar operation, then play back interesting events. The signal processing unit communicates with the operator's notebook, so the operator can view the target tracks and the equipment status, as well as change some set-up parameters, if necessary. The radar can operate at a maximum antenna rate of 60 rpm, providing a coverage as shown below, but it can as well be operated at a slower scan rate, with the coverage correspondingly extended. For example, a 20% increase in detection range (and height) will occur when the antenna rate is 30 rpm.
