IF Signal Processing
The starting point for RVP900 computations are the instantaneous IF-receiver samples p
n
and, the instantaneous burst-pulse or COHO reference samples b
n
.
These data are available at a very high sampling rate (up to 100 MHz), which makes possible
the digital implementation of functions that are traditionally performed by discrete
components in an analog receiver.

FIR (Matched) Filter
RVP900 implements a digital version of the matched filter that is found in the traditional
analog radar receiver. The filter length (number of taps), center frequency, and bandwidth
are adjustable.
The overall spectral purity of the FIR
filter is typically greater than 84 dBc.
