Vaisala Sigmet Digital Receiver and Signal Processor RVP900

The RVP900 is a digital receiver and signal processor designed for weather radar applications, offering comprehensive digital intermediate frequency (IF) and signal processing capabilities. It features 100 MHz, 16-bit IF sampling across five independent channels, enhancing sensitivity and dynamic range. The device operates on an open Linux PC platform, allowing for integration with custom software or the optional IRIS software. The RVP900 supports independent and parallel finite impulse response (FIR) filtering, enabling dual pulse width and dual frequency strategies on each receive channel. It is equipped with an Ethernet interface for PC independence and can handle a maximum range of up to 1024 km with a minimum range resolution of 15 meters. The system is capable of processing up to 38.4 billion multiply/accumulate cycles per second, making it suitable for high-performance applications. The RVP900 also includes features for dual polarization and pulse compression, with a dynamic range exceeding 105 dB. Its environmental specifications allow operation in temperatures ranging from -40¬8C to +50¬8C, depending on the power option. The device is designed for reliability, with a mean time between failures (MTBF) of over 50,000 hours at 25¬8C.
