Abstract
Abstract A processing device for stretching video signals in a pulse radar system between the output of the receiver of large pass bandwidth and exploiting means such as an oscilloscope. A delay line connected to the output of the receiver provides a plurality of output signals to an non-linear circuit which transmits, to said exploiting means, only the signal having the greatest amplitude and blocks the other signal for preserving the signal to noise ratio.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
122 words
A processing device for processing video signals in a pulse radar system, between an output of the radar''s receiver which has a determined pass-band width (B) and an input of exploiting means having a narrower bandwidth (b), said device comprising: delay means having an input connected to the output of said receiver and a number of outputs for delivering a plurality of output signals, the number of outputs being equal to the whole number closest to the ratio of the pass band, B/b, and non linear circuit means connected between the outputs of said delay means and said exploiting means, for transmitting, amongst the output signals from said number of outputs, the signal having the greatest amplitude and blocking the other signals.
Claim 2
Dependent Claim
122 words
A processing device for processing video signals in a pulse radar system, between an output of the radar''s receiver which has a determined pass-band width (B) and an input of exploiting means having a narrower bandwidth (b), said device comprising: delay means having an input connected to the output of said receiver and a number of outputs for delivering a plurality of output signals, the number of outputs being equal to the whole number closest to the ratio of the pass band, B/b, and non linear circuit means connected between the outputs of said delay means and said exploiting means, for transmitting, amongst the output signals from said number of outputs, the signal having the greatest amplitude and blocking the other signals.
Claim 3
Dependent Claim
36 words
A device as claimed in claim 1, wherein said non-linear circuit means comprises a plurality of diodes, one diode being connected respectively between each output of said delay means and the input of said exploiting means.
Claim 4
Dependent Claim
25 words
A device as claimed in claim 1, wherein individual amplifying means are arranged between each output of said delay means and said non-linear circuit means.
