Simulation on characteristic of angle-tracking for semi-continuous wave radar

Abstract

The distance shield problem may occur with the use of high-PRF semi-continuous wave radar. The conventional solutions are to employ an uneven PRF wave, which increases the complexity of the equipment. Thus, a blind tracking arithmetic, which is implemented by combining /spl alpha/-/spl beta/ filtering arithmetic with smooth extrapolation, is put forward. The arithmetic has been simulated in the Matlab Simulink environment The simulation result proves the validity of the arithmetic in various noise conditions, especially in the period of the distance shield problem.
