Analogue This
board
is
mounted
directly
on
Analysis
and
enclosed
in
a
screening
can.
It
receives
the
raw
Doppler
signals
from
the
array
and
delivers
filtered,
amplitude
compressed
Doppler
signals
to
Analysis.
Input Selection Switch Used
to
select
one
of
three
possible
inputs
to
Analogue.
• Raw
Doppler
signals
from
the
array
antenna
• An
externally
generated
signal
connected
at
the
external
input
connector
of
the
RADAR.
• An
internally
generated
test
signal
provided
by
Analysis

Band Pass Filters The
band
pass
filter
is
realised
as
the
cascade
of
a
HP
VCVS
stage
and
a
LP
GIC
stage.
Both
stages
realise
a
C
05
20
%
30°
response
with
a
minimum
design
attenuation
of
60
dB.
These
circuit
topologies
were
chosen
in
order
to
assemble
the
filter
using
a
single
capacitor
value
with
5
%
tolerance.

The
VCVS
input
stage
includes
26.8
dB
gain.
Combined
with
the
6
dB
insertion
loss
of
the
output
GIC
stage
the
total
gain
is
20.8
dB.
Using
standard
1
%
resistor
values
and
10
nF
COG
capacitors
the
*3
dB
frequency
of
the
two
stages
are
1164
Hz
and
11.3
kHz.

Signal Compression (AGC) The
AGC
stage
is
based
on
a
variable
gain
amplifier
with
a
gain*adjustment
range
of
0
dB
to
+80
dB.
Its
output
is
converted
to

Pass REVISION SUMMARY – The following changes have been made to this Report: Date Project No. Project Handler Page(s) Item Description of Change Report Number 3167233BOX-001 Page 5 of 39 3.0 Sample Calculations The field strength is calculated by adding the Antenna Factor and Cable Factor, and subtracting the Amplifier Gain (if any) from the measured reading. The basic equation with a sample calculation is as follows: FS = RA + AF + CF - AG Where FS = Field Strength in dBμV/m RA = Receiver Amplitude (including preamplifier) in dBμV CF = Cable Attenuation Factor in dB AF = Antenna Factor in dB AG = Amplifier Gain in dB In the following table(s), the reading shown on the data table reflects the preamplifier gain. An example for the calculations in the following table is as follows. Assume a receiver reading of 52.0 dBμV is obtained. The antenna factor of 7.4 dB and cable factor of 1.6 dB is added. The amplifier gain of 29 dB is subtracted, giving a field strength of 32 dBμV/m. This value in dBμV/m was converted to its corresponding level in μV/m. RA = 52.0 dBμV AF = 7.4 dB/m CF = 1.6 dB AG = 29.0 dB FS = 32 dBμV/m Level in μV/m = [10( 32 dBμV/m)/20] = 39.8 μV/m The following is how net line-conducted readings were determined: NF = RF + LF + CF + AF Where NF = Net Reading in dBμV RF = Reading from receiver in dBμV LF = LISN Correction Factor in dB CF = Cable Correction Factor in dB AF = Attenuator Loss Factor in dB To convert from dBμV to μV or mV the following was used: UF = 10 (NF / 20) where UF = Net Reading in μV Example: NF…
