However, Queen Camilla was absent from the start of proceedings due to a lingering chest infection contracted last month.
On Wednesday, the emir will visit the Royal Military Academy Sandhurst in Berkshire, where he used to study.
The Princess of Wales greets dignitaries as she arrives for the ceremonial welcome for the Emir of Qatar at Horse Guards Parade.
Queen Camilla was originally set to attend, but pulled out after picking up a chest infection following her overseas visit to Australia and Samoa.
Camilla missed the open-air arrival ceremony for the Qatari emir but was expected to attend lunch at the palace as well as the banquet.
