Abstract

The frequency diverse array radar has a linear increasing frequency offset between the array elements, which produces a range-angle dependent beampattern. And it overcomes the disadvantages of the phased-array providing range-independent beampattern and offers many promising advantages for radar applications. Fast Fourier Transform was considered on beamforming to improve the efficiency of algorithm. Due to the linear frequency offset between the array elements, each element carry out Phase compensation. Then beamforming using FFT algorithm. As the array element increasing heavily, this algorithm can reduce the operation and improve the running speed effectively as data show. In addition, this algorithm reduces the requirement of hardware and can be realized easily.
