An antenna diversity receiver is disclosed. The diversity receiver has a multipath detector for controlling an antenna selective switching circuit. The switching circuit couples one of a plurality of antennas to a RF receiver input. The receiver allows suppression of adjacent channel interferences without unwanted side effects by employing a switching disabling circuit to automatically disabling the switching circuit when the signal delay between the occurrence of multipath distortions in the RF reception signal and the switching between antennas exceeds a predetermined critical signal delay value.

The invention relates to a fitting part in a tank truck, in particular to a waving resistance device in the tank truck and the tank truck with the same. The waving resistance device comprises a main body and a fixing base, wherein the fixing base is arranged at the top of the main body and is provided with an air inlet-outlet servo control device, and the main body is a soft air-tight capsule body. The waving resistance device is made of soft elastic materials instead of a traditional waving resistant plate made of hard materials, such as metal and the like, thereby performing the upgrade from a one-dimensional waving resistance to three-dimensional waving resistance, effectively absorbing the energy of fluid waves in the tank, reducing impact to the tank from waves, improving the effect of the waving resistance and ensuring the service life of the tank and the stable running of the tank truck.

A Doppler sensor operates by transmitting pulses at non-uniform intervals. Samples reflected by an object are processed by multiplying each one by first and second coefficients c_xk and s_xk, the products being separately summed to form two measures which are examined to determine whether an object exhibiting a particular Doppler frequency f_x has been detected. The samples occur at non-uniformly spaced times t_xk such that the average of a cosine wave of frequency f_x sampled at said times t_xk would be substantially zero and the average of a sine wave of frequency fx sampled at said times t_xk would be substantially zero.
