Abstract. The algorithm of formation of a test file of readout of the signal simulating the response on an exit of a frequency-dependent part of the onboard radar-tracking gauge of continuous wave from the moving dot target at an irradiation by its probing periodic chirp signal is offered. Analytical expression of a difference of frequencies and phases of a simulated signal, and also its spectrum is received. Questions of generation of sequence of digital readout and the account of casual value of an initial phase of a probing signal in the beginning of the periods of modulation are considered. The received algorithm can be used in akusto - and hydrolocations, and also for calculation of basic functions at CW SAR.

Keywords: the onboard radar-tracking gauge of continuous wave, a test file of the signal simulating, chirp signal.
