The sentence below:
Our method cannot achieve 100 percent accuracy as compared to DART method due to the imprecise modeling.
Why does the sentence above use as compared to? Can we use as compare to instead?

The phrase "as compared to..." is correct. "As compare to..." would not be accepted as correct by any English speaker.
The above sentence is incorrect. Compared is not an adjective, it is an ordinary verb, hence the adverb as is used mistakenly. The sentence should read:
Our method cannot achieve 100 percent accuracy compared to DART method due to the imprecise modeling.
Compare = to examine (two or more objects, ideas, people, etc.) in order to note similarities and differences: to compare two pieces of cloth; to compare the governments of two nations.
(The construction as [adjective] as is common when comparing two things or people for example: "Our method is as accurate as theirs.")
from Dictionary.com:
The traditional rule about which preposition to use after
comparestates that compare should be followed bytowhen it points out likenesses or similarities between two apparently dissimilar persons or things: "She compared his handwriting to knotted string."
EDIT: I must be more careful before making sweeping statements such as "compared" is not an adjective, it is not as clear-cut as that. Kiamlaluno has provided a clear and very comprehensible explanation on "compared to" and I would like to copy his answer here so that others may benefit.
"Compared is the past participle of compare and "compared to the DART method due to the imprecise modeling" is a participial phrase. Participial phrases function as adjectives; in your sentence, it modifies our method."

You can't use "compare". When you use the verb form "compare" it is a finite form of present tense that needs a subject such as a pronoun (I, you ...). It might also be an imperative when it is the first word of a sentence and it might also be a subjunctive form when used in a subclause after special verbs.
