摘要

Given platform velocity and radar system parameters, the location of clutter in angle-Doppler space is known in airborne radar. For this paper, we designed a two dimensional two-pulse clutter canceller and then an adaptive two-dimensional two-pulse clutter canceller for airborne radar, making full use of this apriori information. First, the clutter model and moving target signal model were formulated in matrix-vector form, and this led naturally to the design of a two-dimensional two-pulse canceller that uses the apriori information. Second, an adaptive two-dimensional two-pulse canceller was derived from the two-dimensional two-pulse canceller by dynamically estimating a two-dimensional two-pulse cancellation from the received data. Theoretical analysis and the results of computer simulations illustrated that the proposed methods have advantageously low computational loads and low data support requirements. The effectiveness of the proposed methods was tested via several experiments.
