Specific Description

This version has a 4 panel antenna and operates at a frequency of 1290 MHz.
 
 
General Description

The LAP3000 is a radar wind profiler that reliably provides continuous and real-time vertical profiles of horizontal wind speed, wind direction, vertical wind speed and turbulence in the atmospheric boundary layer and beyond.
 
The operation is based on the scattering of electromagnetic pulses at inhomogeneities in the air with subsequent Doppler analysis of the backscattered signal. The wind vector is derived using the beam swinging method.
 
The LAP3000 radar wind profiler provides upper-air data with high resolution in time and height. It can substitute extensive radiosonde launching schemes. The LAP3000 works automatically and is virtually maintenance free. It is economic to operate and suited for operation at unmanned, remote sites.
 
The new Digital IF Processor SIRP offers characteristics never found in wind profiler signal processing before. This results in higher data quality, better height coverage and more flexibility to tailor the system output to the user’s specific needs.

Uncompromised Wind Profiler Antenna Concept

The patch array antenna of the LAP3000 has no moving parts, ensures long-term reliability and avoids safety hazards. Using a true vertical beam, vertical wind and turbulence are accurately measured and precipitation is identified. The beams point into perpendicular directions and can be set parallel to the Earth coordinate system North-South and East-West consistent with the meteorological definitions of u and v. A fast switching between beams enhances accuracy in complex terrain. An antenna heating is available to improve system performance in cooler climates.
 
 
A New Digital Signal Processor for Wind Profilers

The new SIRP Digital IF Processor was specifically developed for radar wind profilers. It combines Advanced Coherent Noise Suppression ACNS, vertical signal oversampling, 16 chip binary pulse coding, true Gaussian matched filters, and freely programmable height gates. Vertical range resolution can be set to values finer than 50 m. The revolutionary ACNS cancels distinct radio frequency interferences and improves data quality at sites suffering from radio pollution.
 
 
Comfort and Flexibility: the New Operation Software

The SIRP interfaces to the computer using USB 3.0, supporting highest data rates. With unlimited multiple mode capability, different settings with respect to pulse length, pulse coding and pulse shaping can be operated simultaneously. This allows a single wind profiler to support different applications at the same time. An auto configuration option optimizes the settings without need of user interaction. A variety of graphical data representations, data output formats and data transfer options matches all needs.
 
 
RASS Extension Available for Precise Temperature Measurements

A RASS extension is optionally available to make the radar wind profiler a combined RASS wind and temperature profiler. The accuracy of the RASS temperature measurement is far better than that of any other remote temperature measurement technique.
