In a moving target indicating pulse radar systems in which echo signals from 5, 6 are delayed in device 10 for a period equal to the interval between successive pulses transmitted via 3, 2 and 1 and subtracted in 11 from the next echo signal before delaying the latter to provide a signal indicative of moving targets for display device 11 the production of undesired signals caused by variations in the interval between the occurrence of triggering (clock) pulses controlling the modulator 3 and the actual emission of a radar pulse from aerial 1 is prevented by means of a compensating variable delay device 7 the delay of which is determined by the potential built up across an integrating circuit 14, 15 in the interval between the occurrence of a clock pulse and the reception by the receiver 6 (or by a separate receiver) of the transmitted energy. Delay device 7 may comprise variable capacitance diodes or may comprise a'set of fixed delay sections switched in or out by the output of amplifier 16 after conversion to a binary code signal. In another form of the invention, the phase of the pulse from delay device 10 may be compared with that of the next pulse (e.g. by means of a circuit similar to a range gate) and the difference arranged to insert a corresponding delay in the input to the comparator. Alternatively, a small fixed delay may be inserted in one path and a variable delay of up to twice that of the fixed delay inserted in the other path. If the echo signals occur very soon after the transmitted pulses equal fixed delays may be inserted in both paths.
