International Telemetering Conference Proceedings / October 28-31, 1996 / Town and Country Hotel and Convention Center, San Diego, California / It is well known that the pulse telemetering system whose system equipment is simple is
superior to the continuous one in ultilizing signal power. But in designing a pulse
telemetering receiver the frequency shift problem is often encountered, the shift often
greatly wider than the signal bandwidth is very unfavorable for improving receiver working
sensitivity. Either to limit transmitter frequency stability strictly or to adapt AFC system in
receiver for tracking carrier wave can solve the problem above, the AFC system method
could improve the receiver’s performance, but the equipment is complicated. To what
extent the receiver working sensitivity will be effected and how to judge the effection in
case of adapting VF matched filter and RF being wideband in receiver are this paper’s
emphasis. In this paper the power density spectrum distribution of the white noise which
has passed through the non-linear system-the linear detector is analysed theoretically, and
the improved working sensitivity of the receiver with video matched filter and its
difference sensitivity value to that of the optimal receiver are derived. The tested working
sensitivity data of two kind pulse receivers with different RF bands are given and the
theoretical calculation results conform well with these data, thus it is proven that adapting
video matched filter in pulse receiver is a effective approach for compensating the receiver
working sensitivity dropping from RF bandwidth increase.
