FIELD: radio engineering, communication.
SUBSTANCE: each pulse in this sequence has a specific constant phase corresponding to a quadratic phase sequence, and this phase is applicable to each pulse in some first modulation sense. This method includes the operation of modulating a reflected energy signal received from one or more objects reflecting a transmitted repeating sequence of N pulses of constant frequency in some second modulation sense, counterposed to said first modulation sense. Method includes the operation of producing N unique and discrete frequency transfers of received reflected energy signal from modulated received reflected energy signals as a function of range r to reflective objects whose magnitude is a multiple of 1/NT Hz, and these frequency transfers can store the spectrum of received reflected energy signal, forming in combination a complex frequency spectrum of signal.
EFFECT: increasing the reliability of received signals by storing the frequency band of reflected signal.
