"The Sierra Nevada Corporation, meanwhile, make a system called Gorgon Stare, named after the female figure in Greek mythology with hair of live snakes who turned those who looked on her to stone. Aimed at surveilling whole cities to build up patterns of supposedly ‘normal’ life against which the ‘abnormal activities’ of ‘targets’ might be identified, the company claims that the system can completely survey a 4 km radius."

I couldn't understand the emphasized phrase, can someone rephrase it for me? Thanks in advance.

In order to identify abnormal behaviour, you first have to know what normal behaviour looks like. A normal pattern of behaviour is the way everything you do fits together - your life. A person out shopping may walk slowly and stop frequently at shop windows. A driver looking for a parking space may drive around the area two or three times and then park. That is a normal pattern of behaviour.

The automated surveillance system has to learn this - it has to gradually build up its knowledge of what normal behaviour looks like.
Only when it has built up its knowledge of normal patterns can it use surveillance to match what it sees against what is normal. Then it can identify "this behaviour is not normal - this person might be a criminal/terrorist - a "target" we have to watch more closely".

I would like to enlighten more with TFD:
build up
1. To develop or increase in stages or by degrees: built up the business; building up my endurance for the marathon.
2. To accumulate or collect: sediment building up on the ocean floor.
3. To bolster: build up the product with a massive ad campaign; built up my hopes after the interview.
4. To fill up (an area) with buildings.
It sems to be that to construct would be the ideal term to replace this phrasal verb, if you wanted.

Here it is as much 'accumulate' as construct. They don't construct the patterns. They just collect lots and lots of data, so they have good algorithms for their program. The more data you have, the better your computer model will be.

Then all that terrorists will have to do is to put a bomb in a taxi driver's trunk.

Looks much more like a surveillance tool than a meaningful anti-terror one.
