A Scheme of Ground Velocity Measurement Assisted by Missile-Borne Radar

Abstract

In order to solve the problem of precise navigation of long endurance missile when satellite signal is unavailable, an integrated scheme for ground velocity measurement of carrier by using missile-borne guidance radar is proposed. The calculation methods of three-dimensional ground velocity measurement with "X" and "T" antenna layout are deduced. The antenna beam parameters, waveform parameters, RF components and signal processing architecture are designed. The measurement error of the system is analyzed. The results show that the auxiliary measurement of carrier ground velocity can meet the needs of carrier navigation velocity correction and improve the equipment integration.
