Abstract
An input tracking threshold detector includes a first circuit receiving input signal, a feedback signal, and a predetermined gating signal. The first circuit outputs a binary signal which during gating signal enablement intervals is indicative of the relative amplitudes of the input and feedback signals. The feedback signal is developed from the first circuit output by a second circuit whose output signal amplitude is indicative of the duty cycle of its input.

In a radar system including receiver means, and detector means for providing a video signal S.sub.i from the receiver means output, the improvement comprising, in combination,
- first means for generating a gating signal S.sub.g having enablement intervals occurring in a predetermined time relation to the transmitted signal,
- second means for receiving S.sub.i, S.sub.g, and a feedback signal S.sub.f, and outputting a signal S.sub.n which, during the S.sub.g enablement intervals, is a binary signal indicative of the relative amplitudes of S.sub.i and S.sub.f, and
- third means for receiving S.sub.n and outputting the signal S.sub.f, S.sub.f being indicative of the duty cycle of S.sub.n.
An input signal tracking threshold detector comprising:
- a. first circuit means for receiving (i) the input signal, S.sub.i, (ii) a feedback signal, S.sub.f, and (iii) a predetermined gating signal, S.sub.g, and outputting a signal S.sub.n which, during enablement intervals as controlled by S.sub.g, is a binary signal indicative of the relative amplitudes of S.sub.i and S.sub.f, and
- b. second circuit means for receiving S.sub.n and outputting the signal S.sub.f, S.sub.f being indicative of the duty cycle of S.sub.n.
