Analysis of Autodyne Signal from Distributed Reflecting Object

The autodyne signal features revealed for the radar environment model considered demonstrate that in the autodyne short-range radar with Doppler target selectivity it is necessary to take into consideration the presence of combinative signal interference from the separate reflecting objects. In order to improve the resolution ratio and noise immunity of autodyne short-range radar, it is necessary first of all to take action to decrease the value of autodyne oscillation frequency deviation. In this way it is expedient and promising to use the stabilized double-diode and biharmonic autodynes providing much better spectral structure of autodyne signal.
