Question #172572

Consider a continuous wave (single tone)

transmitted waveform of carrier frequency . The signal impinges on a target, moving

with radial velocity , and returns to the radar. The resulting signal, after down-

conversion from an IQ quadrature receiver, is given by

In the above expression, is the strength of the returned signal, is the positive

Doppler shift due to the targetâ€™s radial motion and t is the slow time. The signal over

a duration of T is digitized with a sampling frequency . Process the signal using

Fourier transform to obtain the correct estimate of the target velocity. Use the

values in the table below.

S. No. Parameters Values

1 Carrier frequency ( 5 GHz

2 Sampling frequency (.) 500 Hz

3 Dwell time (T) 1 second

4 Target return strength () 1 Volt

5 Radial velocity (,) 3 m/s
