The invention provides a method for determining loop parameters of a phase-locked receiver and a parameter calculator. Step 1, initialize condition parameters, and test loop components to obtain loop component index data; Step 2, set a first-order active filter The resistance and capacitance parameter of; Step 3, according to the resistance and capacitance parameter of described condition parameter, loop component index data, first-order active filter and preset rule and obtain the loop parameter of phase-locked receiver, described phase-locked receiver The machine loop parameters include SSB loop bandwidth, natural resonant frequency, damping coefficient, loop input signal-to-noise ratio, loop signal-to-noise ratio, steady-state phase error, and fast capture band; step 4, judge whether all are satisfied at the same time: The loop signal-to-noise ratio is greater than 6dB, the damping coefficient is within the range of 0.65-0.75, and the steady-state phase error is less than 20°. If both are satisfied, output and / or save the phase-locked receiver loop parameters.
Description
technical field [0001] The invention relates to the field of phase-locked receivers, in particular to a method for determining loop parameters of a phase-locked receiver and a parameter calculator. Background technique [0002] Phase-locking technology originated in the 1930s and began to be applied in the early 1950s, and the technology has been very mature since its development. Due to the needs of aerospace technology, phase-locking technology is widely used in space electronic systems, whether it is starships or ground electronic equipment. Especially after the phase-locked receiver is successfully applied, the performance of the space electronic system has been greatly improved. The USB (S-band unified measurement and control system) transponders in the field of satellite measurement and control in my country all adopt a phase-locked receiver structure. The working principle of the X-band phase-locked receiver is the same as that of the USB phase-locked receiver. The d...
