In PCR process, you don't know the sequence of target DNA, how can you design a primer combined the end of it?

Edit June 6, 2021: the PDF is no longer accessible. I have put the main content of the SOP here: Lowly undergrad has trouble finding good primers for Professor!
Please also take a look at my own standard operating procedure for designer primers (and/or a probe), which includes the use of Primer3: https://www2.le.ac.uk/centres/cancer/internal-information/procedures/sops/sop646v01.pdf

Please read How To Ask Good Questions On Technical And Scientific Forums. I will have a try at interpreting your question:
You don't know the sequence of the putative target region, but you know the flanking sequences. If so, concatenate the flanking regions with a bunch of Ns in the middle, use primer3 to design primers, and put the Ns inside brackets
[NNNNN]so primer3 designs the primers around this region.
