PULSE DOPPLER RADAR

Radars with Pulse Doppler technology developed by LEEYOUNG SND is divided as follows

  • SD-10 Sea State Detector, which can measure and provide data on waves in real time
  • SR-20 Sea Surface Surveillance Radar, which can detect and track micro-marine targets such as periscopes, swimmers, and floats in real time.
  • IR-30 Intruder Identification Radar, which can precisely detect, track and identify intruders such as humans and animals.

※ The PULSE DOPPLER RADAR is the equipment with excellent expandability that can be used in various fields and provides excellent target recognition for small mobile targets at medium and short distances

SD-10 SEA STATE DETECTOR

The SD-10 Detector can quantitatively measure the wave height, wave direction, wave length, wave cycle,
using the latest Doppler processing functions for wave measurement
In particular, its precise wave measurement and wave height information acquisition capability can be
utilized as maritime status observation, coastal erosion monitoring, swell-like wave detection,
ship’s navigation safety system and marine pollution monitoring system.

Major Features of SD-10 DETECTOR

SR-10 SEA SURFACE SURVEILLANCE RADAR

The SR-10 Radar can be installed on the coast & riverside or loaded on a ship to detect,
track and identify ultra-small mobile targets such as swimmers, marine drifts, and submarine periscopes.
In particular, it can be used for the surveillance of swimmers leaving the safety area of the
beach and search and rescue of missing persons in case of marine accidents, it can be not only applied
for infiltration surveillance on coasts, riversides and military ports, but also detecting and
identifying submarine periscopes on a warship for military purposes.

IR-10 INTRUDER IDENTIFICATION RADAR

IR-10 Radar offers the surveillance function for outskirts of various facilities
from small farms to large scale security facilities In particular, this radar can be useful for
protecting national important facilities and military facilities such as airports and nuclear power plants.
When applying this radar to the intrusion detection system(PIDS), it can detect,
track and identify intruders and it can even detect the outskirts of the surveillance area,
intruders can be identified before trespassing the site
