High SNR = Fast Detection
Copyright © Metawave - All rights reserved.
250 m (not to scale)
Assumptions
FMCW modulation Velocity resolution of 0.3 m/s(~1 km/h) Single chirp sequence time ~ 7 ms SNR of detector = 7 dB (11 dB ideal)(ensures high probability of detection)
Radar cross section of target ~ 4 m2
DBF
Analog/WARLORDTM
250 chirp sequences x 7 ms = 1.75 seconds
4 chirp sequences per scan angle
(N_chirps x 7 ms x N_angles + [beam switching time])=(4* 7ms*5) + (5* 3µs)
~140 milliseconds
Analog is an order of magnitude faster than DBF6/26/2018 12
