Alternative solutions for Hilbert filtering in a pulse compression radar

Hilbert filtering and pulse compression may be combined into one module by modifying the pulse compression. Three methods for doing this have been devised, and their relative merits investigated. The first of these results in the most straightforward implementation, the second is more efficient in terms of required hardware, and the third is most suitable for adaptive applications (i.e. applications in which a new reference spectrum must be determined relatively often). The arithmetical efficiency of all three solutions is about the same and is practically equal to that of pulse compression alone. Moreover, all three solutions can cope with high relative signal bandwidths, close to 100%
