Log-periodic and Yagi antennas have been employed to work in CW at 1 GHz and 435 MHz, respectively. The TX and RX antennas have been mounted at 1.35 m above the ground and located at 0∘∘ azimuth and 0∘∘ elevation. RG213 coaxial cables have been used to feed the antennas, ...
The block diagram of fault detection and recovery is shown in Figure 3. Before the Doppler radar and odometer outputs are input into the local filter, the residual chi-square test in b-frame is used to pre-detect the abrupt fault. If the sensor is judged to be faulty during the pre-det...

Referring to FIG. 5, the floating point number510is a power value, and is converted to a dB value580. It should be recalled that a power value P is converted to dB as 10*log 10(P). The floating point number510includes a sign bit512, an exponent (a biased exponent in this case, ...
Figures 3 and 4 show the block diagram of a lidar according to the invention; FIGS. 5, 6 and 7 show the measurement signals in three different cases, the first without frequency adjustment, the second by shifting the frequency by one positive value and the third by shifting the frequency ...
