Abstract
A pulse radar apparatus is provided with a transmitting unit (4) for the transmission of a modulated transmitter pulse Y.sub.t, a mixer (9), an IF amplifier (11) and a quadrature detector (12) for the reception of signals Y.sub.r and the correlation of signals Y.sub.r with a replica X of the emitted modulated transmitter pulse Y.sub.t, to obtain an in time compressed correlation signal .sigma..sub.xy (.delta.). The pulse radar apparatus is also provided with a pulse discriminator (3) to enable, on the basis of at least one amplitude .vertline.Y.sub.r .vertline. of the received signal Y.sub.r and at least one amplitude .vertline..sigma..sub.xy (.delta.).vertline. of the correlation signal .sigma..sub.xy (.delta.), differentiation between the signals Y.sub.r, possessing modulation, and interference.
