Abstract

The range resolution of radar is in inverse proportion to the bandwidth of transmitted signal. But the synthesized bandwidth of stepped frequency signal is limited in practice considering engineering realization. It is a problem to improve the range resolution of the stepped frequency radar under limited synthesized bandwidth. In this paper, we applied the RELAX algorithm to super-resolution processing of stepped frequency radar echo. Simulation results approve that using RELAX algorithm obtains higher range resolution than using traditional IFFT algorithm with same bandwidth, and RELAX algorithm can solve the problem that the bandwidth of transmitted signal is limited. Finally, we conclude the advantage and disadvantage of the RELAX algorithm using in super-resolution of stepped frequency radar.
