I am currently working on a project
with the aim to write a Matlab program to be able
to analyse ESM received data.
I have both synthetic
and real data to play with, which has been de-interleavered
and has the following info:
1. Time of arrival
3. Pulse Width
5. Emitter ID
6. Stream ID
7. Confidence (1
So I am basically number crunching
in software, with no consideration to hardware.
The tricky part comes in the form of missing pulses
or gaps in the stream.
I can assume the PRI of
pulses by looking at one stream and calculating
the median between TOA.
I have to find a
way to compare fragments of streams together to
determine whether they are in fact from the same
I know of ways to fill the gaps
with null data then use various techniques such
as Discrete Fourier to 'estimate', but my objective
is to compare fragments.
I have already written
code to filter the data down and provide a user
interface for streams/certain emitters to be analysed.
Just wondered if any one had any ideas for
comparison methods - I've been told that a similar
technique is used in DNA matching?!?
