Moving target indication radar

A moving target indication radar (MTI) having a high azimuthal position detection accuracy. The received radar return signal is separated into quadrature components which are each converted to a series of digital samples. A continuous discrete fast Fourier transform is then performed on groups of samples corresponding to a predetermined number of contiguous azimuthal units of identical range producing an equal number of output Doppler frequency components which represent the relative speeds of stationary and moving objects within the contiguous azimuthal units. A new separate transform operation is performed for each new sample received. The transform outputs are processed to separately detect the stationary and moving objects.
