Some of the big topics are skipped. The energy of a radar return decreases as the fourth power of the range, which is why you put megawatts out and get microwatts back. There's not much on electronics - nothing about how such big pulses are generated, or the clever trick which allows transmitters and receivers to share an antenna without blowing out the receiver. As is common in USSR publications of the period, examples are from US systems, so as to avoid security problems. Phased array radars are discussed, but not much is said about how the work. That was a touchy subject back in 1974; all the big players had phased array radars, but the technology was classified.
(That led to a suppressed invention - Airadar. In 1973, Rufus Applegarth, who'd had a long career developing avionics, developed a low-cost phased-array radar with a conformal antenna (not a dish, part of the leading edge of the wing) and electronic scanning (no moving antenna) and mounted it on a single-engine plane. It worked great, and Flying Magazine had a chance to see it work in flight.[1] The USAF was upset; it was much lighter and smaller than what they had at the time. Airadar was quietly suppressed, and it was years before radars like that appeared on the commercial market.)
