Knowing send-ups

What does "knowing send-ups" mean in the provided context? Does it mean "conscious imitations"?

Context:

While presenting this interpretation of the advertisements in the form of a gentle satire, Lodge draws attention to the extremely specific nature of Silk Cut imagery, which, like that of Dali in particular, trades on sexual anxiety
