1 The Impact of Pulse Compression on Various Altimeter Designs When studying
the possible use of pulse compression in the GEOS - D radar altimeter we
considered the effect of pulse compression on the various radar designs . Aside
In the radar receiver , another dispersive delay line possessing a reverse
dispersion characteristic acted as a matched filter or pulse compressor . A pulse compressor concentrates the energy of a radar echo originally spread over the
REVIEW OF TIME COMPRESSION FILTER THEORY W. Cauerl was apparently
the first to suggest the possibility of compressing a pulse of a sweeping signal by
passing it through a network whose transit time is an appropriate function of ...

If the pulse width narrows , the amplitude of the compressed pulse will increase .
This increase is the same as the compression ratio . In the radar under
discussion , the pulse is compressed by a ratio of 100 : 1 , so the amplitude of the

A study is made of important subsystems for high energy, wide instantaneous bandwidth radar transmitters. The relative merits of direct short pulse operation and pulse compression techniques to obtain high range resolution are explored. Included are the present and predicted capabilities of pulse modulators and r-f sources, design information on electrical breakdown and attenuation of transmission lines, effects of high peak and average power on microwave window materials, and the effects of propagation parameter anomalies on wide bandwidth radar transmissions. Appropriate supporting material such as an introduction to special analytical techniques, and a survey of wideband radar receivers is also included. (Author).
