GENERAL

A radar wind profiler (RWP) is a pulse Doppler radar system, utilized to measure wind profiles from near ground to as high as 20 Km. RWP systems typically operate between 50 MHz and 1.2 GHz, and use phase-array antenna systems. The antenna points vertically, directly above the radar. The new ATI RWPs are designed around original and proprietary antenna, receiver, and signal processing techniques. These new systems have been carefully developed for ease of use, low maintenance and for long-term unattended operation. The overall RWP design can be scaled for high altitude, mid altitude, or boundary-layer coverage, through the use of varied frequencies, antenna sizes and transmitted power. The core technology of the ATI RWP is the data system, which is responsible for the control, signal generation, and basic data processing of the complete radar. Part of the data system software is an Advanced Signal Detection (ASD) module, which performs all of the high-level data processing and uses specialized time-height continuity algorithms to screen out interference and other contaminates to the wind data. Should the customer not have the capabilities to provide maintenance and/or to properly process the data for use in data reports, service contracts are available.

FEATURES

• Modern, state-of-the-art product
• Advanced signal processing techniques to screen out RFI, birds, planes and other data contaminants
• Built-in hardware status monitoring
• Fully automatic, unattended operation
• Remote data displays and controls
• Fully steerable antenna
• Reliable easy to maintain design
• Virtual temperature (RASS) profiling option available
• Easily customized for individual needs

TYPICAL OPTIONS

• RASS Virtual Temperature Profiling System
• Trailer with shock mounting
• Remote communications and data displays
• Country Specific (such as AC power and Transmit frequency)
• Higher power and/or larger antenna
• Other operating Systems or platforms

PRODUCT DIFFERENTIATIONS

The ATI antenna system utilizes full beam steering and individual Yagi or micro-patch antenna elements. This allows the system to have a very good side lobe pattern (over traditional co-co antennas) and will eventually allow for spaced antenna and Velocity Azimuth Display (VAD) signal processing techniques with little or no changes to the antenna. The antenna also utilizes solid-state phase-shifters for high reliability.

• The data system utilizes commercial off-the-shelf data acquisition cards. Many RWP vendors utilize proprietary cards, which are only utilized for their systems.
• The ATI data system can run under Windows or Linux. Should a customer require a specific operating system, this might help.
• Full system health monitoring is standard for the ATI systems. This is often an expensive extra for some vendors. Because of this, calibrated Cn² (turbulent intensity) can be offered
• The ASD package (multi-peak analysis and final QC) also comes standard with the system. Again, this is often an expensive extra for ATI competitors.
• ATI has a good reputation for customer service.
