Title:
RADAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2001/007930
Kind Code:
A1
Abstract:
A switch (16) switches transmission antennas (18a, 18b) alternately for transmission. A signal received by a receiving antenna (20) is supplied to a radar signal processor (10) through a homodyne detector (24) and a comb filter (26). The comb filter (26) has a characteristic synchronous with the switching rate of the switch (16) and removes leaky transmission waves modulated with the switching rate, thus removing adverse effects of leaky waves derived from the modulation by antenna switching.
