1. A detection and ranging system comprising:

  • M transmitting sensor elements configured to transmit a probe signal;

    N receiving sensor elements configured to receive an echo signal generated upon reflection of the probe signal from a target;

    a matrix generator configured to generate a third matrix by multiplying a first matrix by a second matrix, the first matrix including as diagonal components L received signals obtained from an effective receiving sensor array formed by synthesizing the M transmitting sensor elements and the N receiving sensor elements, the second matrix being formed of P L-dimensional vectors that are linearly independent of each other, P being an integer that is smaller than L; and

    an estimator configured to estimate a direction of arrival of the echo signal from the target according to a pseudo covariance matrix generated by multiplying the third matrix by Hermitian conjugate transposition of the third matrix.
