METHOD AND SYSTEM FOR MODELING RF EMISSIONS OCCURRING IN A RADIO FREQUENCY BAND

摘要

The method and system for modeling RF emissions occurring in a radio frequency band utilizes commercial off-the-shelf (COTS) hardware to perform the steps of converting legacy PDW databases to RF signal I and Q format and storing the I and Q data in a digital I and Q data signal library. Alternatively, real-time RF signals are recorded in I and Q format and routed to the library. Moreover, a synthesizer is provided to form I and Q data and forward the data to the library. I and Q library data is time-tagged. An RF editor includes editing tools to modify the I and Q library accordingly, as required. A channelizer extracts channel information from the I and Q data and sends that channelized data to at least one to vector signal generator. A combiner is used to combine outputs of multiple vector signal generators connected to the channelizer.

1. A computer-implemented method for modeling RF emissions occurring in a radio frequency band, comprising the steps of:
storing in-phase and quadrature (I and Q) data associated with the RF emissions in an I and Q signal library; accepting I and Q signal library data edit commands from a user via a GUI interface; modifying the I and Q signal library data according to the edit commands, thereby providing modified I and Q signal library data; storing the modified I and Q signal library data in the I and Q signal library; combining the I and Q data including the modified I and Q signal library data into a composite RF signal modeling the RF band; extracting channel information from the composite RF signal, thereby resulting in channelized RF signal data; and routing the channelized RF signal data to disparate vector signal generators based on the channel information to provide real-world RF emissions based on the RF band modeling.
