Design and EPGA Implementation of Digital Pulse Compression for Band–Pass Radar Signals

摘要

The paper presents fully digitized approach for band-pass discrete coded radar signals. The emphasis is to use onegeneralized reconfigurable compressor for several different types of signals and different types of receivers. It fits for directradio frequency receiver (RF) as well as for intermediate frequency (IF) receiver. The system implementation on fieldprogrammable gate area (FPGA) let us eliminate special chips previously needed. From the experimental results it is knownthat this approach appears to work well for matched and mismatched pulse compression and it outstands when timebandwidth product (TB) is of order 1000. A precision of 14 bits has been considered in the input signal and 16 bits in thefilter coefficients. It gives the dynamic range of 78 dB and the quantification error less than 0.012 %.
