A tight 0.5 ft dead-band maximizes filling tank capacity, and Echo-safe calibration eliminates false echo signal
returns while fail-safe intelligence provides for maximum process safety.
It is mounted in a compact enclosure and is designed to electronically attack the Lab-Volt Tracking Radar by masking the target echo signal
with noise and cause range or angle deception.
Of course it is observed only from the current echo signal
. Consider this problem in another way.
For this purpose, the echo signal
model of the MIMO radar with orthogonal frequency division multiplexing linear frequency modulated (OFDM-LFM) waveforms--termed OFDMMIMO radar--is presented first.
We demonstrated that ultrasonic waves, properly processed and delivered into the inferior colliculus, by means of implanted electrodes, gave rise to a brain response modulated by echo signal
features suggesting that spatial information sent by our stimulation signal was efficiently interpreted and encoded by the auditory system.

From the curve of displacement versus time in Figure 4, it can be seen that there are two groups of sine signals with ten cycles which are the passing signal and end echo signal
Similarly, we can get directly-reflected path echo signal

The received echo signal
was amplified (20 dB), bandpass filtered (1-35 MHz) by the pulser-receiver, and then displayed (500Ms/s) on a digitizing oscilloscope (Model 9374L, LeCroy, Chestnut Ridge, N.Y.).
These four complex numbers represent the amplitude and phase (or in-phase and quadrature components) of the received target echo signal
for the specified combination of transmitter and receiver polarizations.
Simple detection of the presence of an echo signal
may not satisfy this criterion.
