Radar system with reduced distance error |
摘要 |
In a radar system comprising equipment for transmitting frequency modulated pulses and compressing the received signals in a filter for frequency-dependent weighting, the weighting is asymmetrical in a manner such that the leading sidelobes of the pulse compression signal are reduced and the lagging sidelobes are raised. The reduced leading sidelobes can easily be reduced below an amplitude threshold so that the main echo lobe within the pulse compression signal is reliably acquired for determining the closest target distance. The invention may advantageously be applied to ground tracking radars.
