Brevet Sergeant Doig was killed and Sergeant Michael Hutchinson wounded after they were allegedly shot by Jaydn Stimson, 26, at a rural property in Senior, near the Victorian border, on November 16.
Stimson remains in hospital under police guard and has been charged with murder and attempted murder.
The police investigation is ongoing.
Monday's event will be the second public memorial in as many weeks, after more than 1000 people gathered to mourn the loss of SA police commissioner Grant Stevens' son on Thursday.
Charlie Stevens died on November 18 after sustaining irreversible brain injuries in an alleged hit-and-run incident at schoolies.
Landmarks were lit up in blue in memory of Mr Doig and in support of the police family more broadly last week.
"It's been a weekend in which the preciousness of life, certainly in my little world, has been in full view," SA Premier Peter Malinauskas told ABC radio last week.
"Just how fragile life is and how fortunate we are to experience it and how quickly it can be taken away.
"It's important we savour every moment and value the things that matter most and family is paramount among those."
Blue lights also shone on buildings across Adelaide, including police headquarters, Adelaide Oval, parliament house and Adelaide town hall.

Deputy Commissioner Linda Williams said both Sgt Hutchinson and Constable Rebekah Cass, who was also at the scene of the shooting but was uninjured, were home recovering from the incident.
"(They) placed themselves at great personal risk to render first aid to Brevet Sergeant Doig and handcuff the accused under what was an incredibly confronting and distressing incident," Ms Williams said.
"It is now evident to me that Sergeant Hutchinson and Constable Cass performed their duties on the night with courage and bravery."
Sgt Doig's live-streamed funeral service will be held at 11am at the Adelaide Convention Centre.
The 53-year-old had served in the southeast for more than a decade after taking up a post at Lucindale in 2011.
He joined the force in 1989.
