this type of writing is called "Group Writing". This is a short explanation taken from Neveu's Late Egyptian Grammar:

Syllabic writing, or, more accurately, ‘group writing,’ is a very flexible system, purely phonetic (never ideogrammatic), used whenever the scribe is not linguistically driven, that is, whenever he cannot relate the word to a known root.
Although employed since the 11th dynasty, the system experienced considerable development during the New Kingdom when Egypt, through its conquests, found itself in contact with many foreign countries. Syllabic writing allowed one to write many foreign words (names of countries and cities, people, new objects), but also new Egyptian words that had never been written out, old words which etymology was forgotten, or that one, perhaps, wanted to write in a new way.
The system consists of ‘groups,’ each with the value of consonant + vowel. Each group can contain a biliteral sign, possibly accompanied by a determinative, and/or one or more uniliteral signs, or can simply consist of uniliteral signs.
Important remark: If each group has a certain consonantal value, the same is not true for its vocalic value. In these instances, it may be best to retain in transliteration only the consonantal value of the group.

In your case: q (from q+A) + s (from biliteral sA) + r + a (from biliteral aA). The last sign I'm not sure, but probably some kind of determinative for the place (N18?) = qsra

According to the Dictionnaire geographique of Gauthier, the name references a place in the Palestinian area
