Abstract
A radar apparatus has a code generator, a transmission section, a reception section, a delay section, a despreading processor, a correlation value detector, a target detector, and an adjustment section. The transmission section transmits a signal modulated with a spectrum spread code. The reception section receives a direct wave from the transmission section and a reflection wave of the transmitted signal from a target. The delay section delays the despread code stepwise. The despreading processor performs a despreading processing with respect to a signal obtained from the reflection wave received, with using the despread code delayed. The correlation value detector detects a correlation value from data output from the despreading processor. The adjustment section adjusts a phase shift between the spectrum spread code and the despread code so that a correlation strength of the direct wave is equal to or larger than a predetermined value.
