Abstract
There is proposed a signal processing apparatus for enhancing a target signal and suppressing the remaining components without increasing an array size or the number of sensors. This signal processing apparatus includes a first array processor that generates a first array processing signal by enhancing a predetermined signal among signals received from a plurality of sensors, and a decorrelator that generates a decorrelated signal by removing, from the first array processing signal, a signal component correlated with a signal received from an auxiliary sensor different from the plurality of sensors.
