“…At the same time, the V TR velocity component is very important for determining the direction and overall speed of a radar target, and in the approximation Equation (6), can be determined only from the results of sequential processing of several frames [ 31 ] of the input radio signal. In References [ 32 , 33 , 34 ], to determine the transverse velocity component based on the analysis of data obtained over the time interval of one frame (frame) of a radio signal, parallel processing of echo radio signals reflected from several reflex zones of a radio monitoring object is proposed. This method makes rather stringent technical requirements for the characteristics of LFMCW radars, in particular, the angle resolution and the computational performance of the data processor.…”

A rigorous mathematical description of the signal reflected from a moving object for radar monitoring tasks using linear frequency modulated continuous wave (LFMCW) microwave radars is proposed. The mathematical model is based on the quasi-relativistic vector transformation of coordinates and Lorentz time. The spatio-temporal structure of the echo signal was obtained taking into account the transverse component of the radar target speed, which made it possible to expand the boundaries of the range of measuring the range and speed of vehicles using LFMCW radars. An algorithm for the simultaneous estimation of the range, radial and transverse components of the velocity vector of an object from the observation data of the time series during one frame of the probing signal is proposed. For an automobile 77 GHz microwave LFMCW radar, a computer experiment was carried out to measure the range and velocity vector of a radar target using the developed mathematical model of the echo signal and an algorithm for estimating the motion parameters. The boundaries of the range for measuring the range and speed of the target are determined. The results of the performed computer experiment are in good agreement with the results of theoretical analysis.

“…The precision of this method is limited. The lateral velocity can be estimated based on multiple reflection points of one target [3–5]. This algorithm calculates the radial velocities of some reflection points on a target, measures the azimuth angular of these points, and calculates the velocity of the target according to the geometric relation eventually.…”
