FLAT ILLUMINATION DEVICE HAVING EDGE LIGHTING

The invention relates to the field of radar and can be used in on-board radar stations for determining the coordinates and speed of moving and stationary objects. The technical result which can be achieved is an increase in the accuracy of determining the coordinates and speed of objects and targets having a low level of effective reflective area. The essence of the method consists in assessing the rate of change in frequency of the additional linear frequency modulation (LFM) of a signal reflected from an object and dependent on the movement of the latter, with subsequent calculation of the distance to the object taking into account the value of an initial frequency of the received LFM signal. Said technical result is achieved by the fact that the distance to the object is determined on the basis of a change in the frequency of a probing LFM signal, taking into account Doppler corrections. The method is realized with the aid of a device comprising the following, interconnected in a defined manner: M channels for emitting a continuous LFM signal at various frequencies and polarizations, N channels for receiving echo signals, an N-channel parameter assessment device, an N-channel device for generating supporting functions, a received-signal multiplier with supporting functions, a rapid Fourier transformation unit, a device for searching for the maximum of a mutual correlation function, and a sensor of the intrinsic speed of a radar-station carrier.
